“…Other advantages are applied to active filters. For instance single capacitive layer URC [4], [5] and double capacitive layers URC [6], [7] in conjunction with amplifier in literatures respectively. However, there are some disadvantages due to their magnitude characteristics of the low pass filter at cut off and it attenuation at stop band .The double capacitive layers uniformly distributed RC line are circuit symbol illustrated in where R and C are the value of the total resistance and capacitance of the double capacitive layers URC respectively, a is a ratio of C2 and C1+C2 .…”

The paper describes a frequency discriminator using double capacitive layers uniformly distributed RC network (DURC). The configuration of the circuit consisted of two active DURC notch networks. Herein, the capacitive ratio of the DURC network are used to adjust it steepness of the magnitude slope of a frequency discriminator. It is shown that the output voltage of the circuit has more steepness of slope than does a simple capacitive layer URC. Simulated results of the proposed circuit is investigated.

This paper presents a linear luminance-chrominance gain equalizer for compensating the linear chrominance gain distortion in color TV transmission system. The proposed equalizer was implemented based on Bernstein polynomials. As it is known, the Bernstein type filter has flexible parameters to adjust the circuit performance for the best results. In addition, the modulated 20T sine-squared pulse test signal is generated for testing the proposed equalizer, which can be measured all three types of the linear distortion. As the results, the proposed equalizer is also proved to be efficient in equalizing both the low gain and the high gain chrominance distortions without degraded it phase characteristics.
