Digital filter switch for data receiver |
摘要 |
A digital filter switch for use with a data receiver incorporates first and second squaring units connected to the outputs of first and second band-pass filters tuned to the separation and character frequencies in a signal transmission. The outputs of the squaring units are interconnected via an adder to the input of a low-pass filter, which produces the output data signal.
