Signal filters are used in signal processing circuits

Since a signal filter is an electronic circuit, it makes it possible to remove certain unwanted components and features from a signal. Therefore, it is widely used in medical electronics, electronics and communication systems and it can also be used in signal and image processing systems.

In terms of signal transmission, we generate and receive high frequency signals to get better broadband and send or receive large amounts of data. However, after receiving the signals, the signal filter filters those signals to get the specific desired signal.

At the same time the filters are cost effective as compared to other filters; hence they are very economical and they are effective in rejecting the signals that do not conform to the standards. Therefore, it is widely used in signal processing circuits and data conversion, medical electronic systems.
