摘要: The present video bandpass filter passes a sinusoidal video output in response to a square pulse input. The video band-pass filter rejects d.c. and low frequency signal components as well as noise and spurious signals generated at the transmitting source. The video bandpass filter is comprised of an M-derived filter, a series-tuned notch filter, and a final d.c. blocking series-tuned filter which, together, pass the desired video with minimal distortion.
