No. There is no need for notch filtering with the Bortec AMT-8, or any other system using differential pre-amplification of the EMG signal. Differential pre-amplification allows for the rejection of 50Hz or 60Hz hum (power-line noise) and other external noise sources by rejecting common signal components that are measured from two closely spaced (e.g. 2 cm) electrode sites. One important measure of how well noise components are suppressed is what is termed the common mode rejection ratio.

No! Freezers with "A" or "D" in the suffix at the model number run on 60Hz, "W" or "V" in the suffix indicate a 50Hz supply is required. These units will not operate on the wrong supply frequency, attempting to do so may cause permanent damage and invalidate the warranty.

I think that's going to be unavoidable with HDV. It's rather different to DV. Having the same resolutions in both camps, but different framerates is one thing - but the pixel aspect ratios for the two popular resolutions are different too. Why is 720p square pixels but 1080i 4:3 ones? Go figure... Why is 720p square pixels but 1080i 4:3 ones? Go figure... At the normal resolutions of 1280x720 and 1920x1080, both of the main HDTV formats in their various flavours DO have square pixels.

Induction motors use an iron core and require flux in the iron to operate. In order to achieve the commercial goals of smasllest size and lowest price at best efficiency, induction motors are designed to operate at a high level of flux in the iron. The flux is determined by the turns, voltage and frequency. In a modern motor, if the flux is increased by a small amount, the iron losses increase and the iron tends towards saturation.

It is not necessary to remove your UV filter when you're going to use any other filter you may have, but it won't do any harm. Some filters, like polarizers, do cause image degradation because of their construction. This degradation is usually more than the degradation already caused by the UV filter, so in those cases you do not really have to remove the UV filter. On the other hand, you run the risk of light being 'trapped' between the two filters, thus causing lighter spots on your picture.

The Notch Filter is used to eliminate unwanted acoustic feedback. When amplifying an acoustic guitar there is a great potential for positive feedback from the amplifier to the guitar. Since the acoustic guitar is hollow and usually constructed of fairly thin material it has the potential to resonate at certain frequencies, (usually between 100 - 350 HZ). The Notch Filter is used to eliminate, or filter out, the frequency that will cause the guitar to resonate.

A2) Many Pilgrim Radial Fit Bolts have been supplied for use both on 50HZ and 60HZ rated machines. These would include Nuclear, Hydro Electric and Fossil Plants in USA, Canada, Korea, Taiwan, UK - for Westinghouse, GE, Alstom, Hitachi, MHI, MAN, Parsons, Siemens and Toshiba machines. PILGRIM Radial Fit Bolts have also been supplied to for use on a number of Siemens and MHI Gas Turbines.

Run the codec tweak tool that is included with the K-Lite Codec Pack. It has the ability to disable several DirectShow filters ("DirectShow Filter Management"). Open the GSpot Codec Information tool. In its menu click on 'System', then on 'List Codecs and Other Filters'. If the file is located outside the Windows system32 folder, then you need to use the full path of the file instead of just the filename. If the path contains spaces, then surround it with quotes.

The Olympus E-System features a unique "noise reduction system" that reduces noise without reducing sharpness or color accuracy. Long exposures (two seconds or longer) or high ISO speeds can cause bright or dark points to appear in digital images, a phenomenon called Fixed Pattern Noise.

Bacteria and viruses (including the potentially deadly E.coli) are even smaller than parasitic cysts. Only reverse osmosis systems or water distillers can almost completely remove them, and, in the case of reverse osmosis systems, there is still a chance of bacterial breakthrough, especially when the R.O. membrane ages or otherwise degrades. Adding a UV sterilizer as the final stage of filtration is a very good safeguard.

Sponge filters are great for filtering tanks containing baby fish. Not only can they easily handle the waste the baby fish produce, but sponge filters actually have many microorganisms growing on them that little fish graze upon between feedings. They also won't suck up your baby fish like a power filter will. Sponge filters are also great if you own a large number of aquariums.

Noise is any unwanted sound. Noise can come from loud music, a chainsaw, machinery, guns, or motorcycles .

The Noise Reduction function reduces the noise that is generated during long exposures. When shooting night scenes, shutter speeds become slower and noise tends to appear on images. Turning this function on will reduce the amount of noise in the image.

Elite's Electric Screens use the standard North American voltage/frequency of 110V 60 Hz. Our product is also made in a 220V 50Hz voltage/frequency for the various applicable countries that we export to. In addition to this, we produce a transformer/adaptor (Part#: ZTF220) that will connect our US product to a 220V 50Hz outlet when traveling internationally.

Yes, many products are available in variants to operate on different electrical supplies. As part of the Dynalab catalog number you will see the voltage and hertz (i.e. SRT6/120V/60).

Never - a small instrument vacuums the cloudy lens protein from the eye. It can be powered by ultrasonic energy, though laser energy is being used on a limited basis. But all " vacuums" require a small incision to permit access to the lens.

Yes. You should purchase filters certified by NSF International (1-800-NSF-MARK) to remove arsenic (such as water distillation systems). While such certification is not necessarily a guarantee of safety, it is better than no certification at all. It is critically important that all filters be maintained and replaced at least as often as recommended by the manufacturer; otherwise they might make the problem worse.
