In concept, a sequential circuit uses logic gates to provide the control functions, and it uses flip-flops to store the digital signals. Such a device is used to store one bit of information. One output indicates the true variable of the output, and the other indicates its complement. A flip-flop (ff) is a bistable device that has two outputs. _multivibrator is used as a memory element.A sequential circuit consists of logic gates and flip-flops. The time period of a symmetrical astable multivibrator is 1.38RC. Read More: MCQs on Sound Waves Questions and Answers A 555 IC Timer is used for designing an electronic clock.
