1.	With a 200 kHz clock frequency, eight bits can be serially entered into a shift register in ________(a) 4 μs(b) 40 μs(c) 400 μs(d) 40 msThe question was asked in a national level competition.I would like to ask this question from Shift Registers in portion Registers of Digital Circuits
Answer» Right answer is (B) 40 μs To elaborate: f = 200 KHZ; T = (1/200) m sec = (1/0.2) micro-sec = 5 micro-sec; In serial TRANSMISSION, data enters ONE bit at a time. After 8 clock CYCLES only 8 bit will be loaded = 8 * 5 = 40 micro-sec.
