Question

An 8-bit serial in/parallel out shift register is used with a clock frequency of 2 MHz .Considering the initial value of register is 00000000, the time required to transmit the input 8-bit value to output is _____?​

Answer 1

Answer: c

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.
