1.	An 8-bit serial in/serial out shift register is used with a clock frequency of 2 MHz to achieve a time delay (td) of ________(a) 16 us(b) 8 us(c) 4 us(d) 2 usThis question was posed to me by my college director while I was bunking the class.The origin of the question is Shift Registers in chapter Registers of Digital Circuits
Answer» Right CHOICE is (c) 4 us Easiest EXPLANATION: One clock period is = (^1⁄2) micro-s = 0.5 microseconds. In serial transmission, data enters one bit at a TIME. So, the total delay = 0.5*8 = 4 micro seconds time is required to transmit information of 8 BITS.
