A filter for a pulse form of signal which substantially reduces sidebands, yet provides an output signal which is substantially free of jitter and at the same time has no inter-symbol interference. The filter comprises means for detecting the pulse type of signal and for substituting pp

A filter having an input for receiving a pulse signal form of binary information and an output for providing a synthesized output signal correlated to the input signal comprising: (a) means for comparing the output signal with the input signal one bit at a time, (b) means connected to said comparing

A filter having an input for receiving a pulse signal form of binary information and an output for providing a synthesized output signal correlated to the input signal comprising: (a) means for comparing the output signal with the input signal one bit at a time, (b) means connected to said comparing means and said output for generating a first predetermined output signal waveform when the output signal bit is different from that of the input signal and the input signal is binary “1”, (c) means connected to said comparing means and said output for generating a second predetermined output signal waveform when the output signal bit is different from that of the input signal and the input signal is binary “0”, (d) means connected to said comparing means and said output for generating a third predetermined output signal waveform when the output signal bit is the same as that of the input signal and the input signal is binary “1”, (e) means connected to said comparing means and said output for generating a fourth predetermined output signal waveform when the output signal bit is the same as that of the input signal and the input signal is binary “0”, in which the predetermined output signals are continuous, whereby the spectra and sidelobes of the output signal which is correlated to the input signal are controlled to a predetermined extent.
