Title: Waveform distortion elimination circuit
Inventor: NAGAMINE TAKAARI
IPC: H03H17/06
Filed: 1990-06-15
Abstract: PURPOSE:To amplify a main signal while eliminating its waveform distortion by giving a tap coefficient of the main signal in terms of a sinX/X wave pulse having a frequency band of a video signal among tap coefficients of a transversal filter. CONSTITUTION:Let one sample period of a digital video signal SY, that is, a delay time tau of a delay circuit be tau=1/(4Xchrominance subcarrier frequency) 69.78nsec, then the maximum frequency able to be processed by a transversal filter 5 is 1/(2tau) 7.16MHz based on the sampling theorem. Since the maximum frequency of a video signal of the NTSC system is 4.2MHz, the video signal SY is not lost even when the filter 5 has a low pass characteristic whose cut-off frequency is 4.2MHz by selecting the tap coefficient of the filter 5 in this way. A tap coefficient for a main signal among tap coefficients of the filter 5 is given on a sinX/X wave by using the sinX/X wave pulse having a band of 4.2MHz in the setting of the tap coefficient of the filter 5 to obtain a gain for the main signal in the transversal filter.
