Related QuestionsWhat's the difference between passive and active tags?
Dynamic Bar Code Systems, Inc - Barcoding, RFID and Identifi...Active RFID tags have a battery, which is used to run the microchip's circuitry and to broadcast a signal to a reader (the way a cell phone transmits signals to a base station). Passive tags have no battery. Instead, they draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna. Semi-passive tags use a battery to run the chip's circuitry, but communicate by drawing power from the reader.
Related QuestionsWhat is the difference between active and passive?
FAQActive, or real-time GPS, means you can request and receive location data from your GPS receiver while your vehicle is on the road. Passive, or non real-time GPS, means your GPS receiver stores all location information for you to access at a later time. Normally, a passive receiver transmits this data at the end of the day, when your vehicle returns to your yard. With a passive system, you get all of the same information as the active system, but in a different time frame.

What is the difference between active and passive sensors?
Land Cover Analysis - General FAQsActive sensors pulse energy at a target and measure the return, or reflection. Light Detection and Ranging (LIDAR) and Radio Detection and Ranging (RADAR) are two examples of active sensors. Passive sensors collect the sun's ambient light energy reflected from a surface with no active pulse of energy from the sensor. Film-based and digital cameras, both aerial and handheld, as well as digital satellite sensors, such as Landsat Thematic Mapper, are examples of passive sensors.
Related QuestionsWhat is the difference between an active (amplified) and passive antenna?
GPS Frequently Asked Questions (FAQ)Active GPS antennas include a built-in Low Noise Amplifier which provides sufficient gain to overcome coax cable losses while providing the proper signal level to the GPS receiver. Active GPS antennas require power from the Passive GPS antennas do not include a Low Noise Amplifier and are best suited to GPS applications requiring a short distance, 1 inch to 3 feet, between the GPS receiver and antenna. Passive antennas require an LNA on the GPS receiver.
Related QuestionsWhat is the difference between active and passive transponder technology?
SimonsVoss FAQsActive transponders have their own power supply (battery). Passive cards/chips, which do not have a battery, must be supplied with energy by the reader or lock. Typically active tags have a longer range than passive tags.
Related QuestionsWhat is the difference between active and passive RFID?
Radio Frequency Identification (RFID)Active RFID uses an internal power source (a battery) within the tag to continuously power the tag and its RF communication circuitry that generate the outgoing signal. Active RFID allows extremely low-level RF signals to be received by the tag (since the reader/interrogator does not power the tag), and the tag can generate high-level signals back to the reader/interrogator.
Related QuestionsWhat is the difference between active and passive direct boxes?
Radial JDV active direct box FAQActive direct boxes require power such as a separate power supply, 48V phantom power, or a battery to activate their circuits while passive direct boxes convert the signal from high-Z to low-Z using only a transformer. Passive DI's do not require a power supply to work.
Related QuestionsShould I get an active or a passive crossover?
Car Audio Components FAQ - WikiFAQ - Answers to Frequently A...Active crossovers are more efficient than passive crossovers. A typical "insertion loss" (power loss due to use) of a passive crossover is around 0.5dB. Active crossovers have much lower insertion losses, if they have any loss at all, since the losses can effectively be negated by adjusting the amplifier gain. Also, with some active crossovers, you can continuously vary not only the crossover point, but also the slope.

Cyclatone™ -> F.A.Q.The manual machine mode is featured in both the Basic Model LVM-1518 and the Motorized Model KSA-7781. To use manual mode when using the Motorized Model, simply don't activate the motor, and the movement will be the same as the Basic Model. (It is like having two machines for the price of one!) The resistance adjustment is designed for use only when in the manual machine mode to minimize wear and tear on the motor.
Related QuestionsWhat is the difference between active and passive FTP connections?
ShareIt FTP Frequently Asked Questions (FAQ)Both the FTP client and server processes should be capable of active and passive connections. When a process is in passive mode, it will "listen" (accept incoming connections) on a data port. The active process will then "connect" (outgoing) to that port and the transfer will start. The FTP request command determines the direction of the connection.
Related QuestionsWhat's the difference between active and passive pickups and tone controls?
alt.guitar.bass - THE WEBSITE!In the early days of bass playing, players had instruments that had both passive tone controls (or EQ) and pickups. This meant that the sound from the pickup could only be altered by "cutting" certain frequencies or parts of the tone. Later, manufacturers connected a pre-amp to the passive pickups, which allowed players to not only cut frequencies, but boost certain ones as well. This type of electronics requires a battery or some other power source to function.

FAQ for isdn4linux: hardware: Supported hardware, its specia...active ISDN card handles most of the ISDN connection protocols (dialing, accepting calls, etc.) itself. The card includes a kind of minicomputer with its own software (firmware). With a passive card, the computer in which the card is installed has to perform these functions. In principle, both types are supported by isdn4linux. However, since active cards have non-standard interfaces, a driver can only be made when the producer publishes the specifications for the interface.

Related QuestionsMy instrument is passive. Can I add active controls without having to replace the pickups too?
Frequently Asked QuestionsProbably. Even though they put passive electronics in many instruments, for the most part they used low impedance (active) pickups. These can be wired with either active or passive tone controls. We recommend checking with the pickup manufacturer first before doing any work though. They can tell you exactly which pickups you have and what wiring options are available.

Related QuestionsQ26 - Why use active crossovers when passive crossovers require fewer components and amplifiers?
Frequently Asked QuestionsA26 - Active loudspeakers make very efficient use of amplifier power, allow drivers of vastly different voltage sensitivity to be used together, and give maximum control over the motion of each voice coil. A 2-way speaker with passive crossover, for example, may run into amplifier clipping on a big bass note. In this process the high frequency tweeter signal, which is riding on top of the bass waveform, gets chopped off in the amplifier, causing large amounts of very high frequency distortion.
Related QuestionsI have an active and a passive bass. Which should be used where?
Tonebone Bassbone - Frequently Asked QuestionsBoth can work in either channel. If you are a purist, you may want to have your passive bass in Channel-1 and set it flat. This would allow your amp to control your EQ for this bass. If you want to beef up your passive, then Channel-2 will give you more control.
