notch filter

That is why notch filters are used in intercarrier system.

In order to protect the neighbouring channels a notch filter is used.

A notch filter has a null response at a particular frequency.

A specific frequency is removed using a notch filter.

However, they were expensive and only high-end models used them, while most color sets continued to use notch filters.

Notch filter - attenuation of certain frequencies while allowing all others to pass.

Adaptive algorithms are often used to automatically tune these notch filters.

This limitation may preclude its use in some low-pass and notch filters.

They are specifically used as notch filters.

A very narrow band-stop filter is known as a notch filter.

(Occasionally the colour information was filtered out using a notch filter and is lost.)

However, in the audio band, a notch filter has high and low frequencies that may be only semitones apart.

A narrow band filter, such as a notch filter, requires low damping.

If everything is set ideally, a notch filter at the base station blocks the steady 2,175 Hz tone from going out on the air.

One way to remove the noise is to filter the signal with a notch filter at 60 Hz.

The extreme case when the signal at the channel's center frequency is completely eliminated is known as a notch filter.

Notch filter - rejects just one specific frequency - an extreme band-stop filter.

A notch filter, usually a simple LC circuit, is used to remove a specific interfering frequency.

Optical notch filters rely on destructive interference.

Bass instrument amplification (discusses use of notch filter to prevent feedback)

Most commonly used are high-pass, low-pass, band-pass, shelf and notch filters.

Notch Filter This filter helps remove a small part of the signal that contains excess color information.

A notch filter is a band-stop filter with a narrow stopband (high Q factor).

In well-designed systems, repeaters or radios usually included an audio notch filter that reduced the volume of the tone at the speaker.

He also reasoned that it could be stopped by inserting a very narrow notch filter at that frequency in the loudspeaker's signal chain.
