Abstract

PURPOSE:To obtain the circuit counting the pulse with a given block by a simple element, by constituting the comparison circuit for the difference between the signal passing through two sets of operators and the shift register and the original signal by means of memory. CONSTITUTION:When 1 bit signal serial is fed, the first operational unit AC1 counts the number of ''1'' of the input signal 1 for one frame, and the value 4 is set to the second operationa unit AC2. The signal 1 at present and the signal 2 via the shift register SR are compared with the comparison circuit CP, and the circuit CP feeds the signal 3 any of the count-up, count down or as it is to the second operational unit AC2 depending on the amount of number of ''1'' for the signals 1 and 2. The operational unit AC2 repeats the count up and count down every one bit with the clock 1 of the pulse of one bit rate, the output 5 is inputted to the total memory unit M, and the output 6 is obtained by reading out every one block with the clock pulse 2 of one block rate.
