WebSignal filtering, Signal suppression, Signal processing. In the field of signal processing, a filter is a device that suppresses unwanted components or features from a signal. The most commonly used filters are low-pass, high-pass, band-pass and band-stop. Characteristics that describe filter are its type, cutoff frequency, order (steepness). WebJun 29, 2024 · Low-pass filters always transition smoothly from the passband to the stopband. Furthermore, there is nothing magical about the “cutoff” frequency, which is more accurately referred to as the –3dB frequency, i.e., the frequency at which the magnitude response is 3 dB lower than the value at 0 Hz.

WebNov 16, 2016 · The IF-filter in a communications receive chain is basically a low-pass filter or band-pass filter. It is used for rejecting the aliasing signals along with spurs generated by active components. The spurs include harmonics and IMD products, among others. With the filter, the receive chain can provide signals with higher SNR for the ADC to analyze.
