1.	The S-R, J-K and D inputs are called ____________(a) Asynchronous inputs(b) Synchronous inputs(c) Bidirectional inputs(d) Unidirectional inputsThis question was addressed to me by my college director while I was bunking the class.My question is based upon Master-Slave Flip-Flops topic in chapter Flip-Flops of Digital Circuits
Answer» The correct option is (B) Synchronous INPUTS For explanation: The S-R, J-K and D inputs are called synchronous inputs because data on these inputs are transferred to the flip-flop’s output only on the triggering edge or level triggering of the clock pulse. Moreover, flip-flops have a clock input WHEREAS LATCHES don’t. HENCE, known as synchronous inputs.
