A BCD counter is one of the 4-bit binary counters, which counts from 0 to a pre-determined count with an applied clock signal. When the count reaches the predetermined count value, it resets all theflip-flopsand starts to count again from 0. This type of counter is designed by using 4...
4-bit synchronous UP, 4 bit synchronous DOWN, 4-bit synchronous UP or DOWN,BCD counter, Synchronous decade counter, 2 bit, 3 bit, loadable,Johnson counter, andring counter. Some of them are discussed below.
From the application circuit, it uses a DTMF decoder MT8870 that uses a crystal of 3.57 MHz for generating appropriate frequency for comparing the input audio tones at its pin2 to generate 4 bit BCD code at its output from pin 11 to 14. This BCD data is passed through HEX CMOS inverters...
Design of BCD to 7 Segment Display Decoder Circuit The designing ofBCD to seven segment display decodercircuit mainly involves four steps namely analysis, truth table design,K-mapand designing a combinational logic circuit using logic gates. The first step of this circuit design is an analysis of...
