Hi Guys,
Some interesting Questions will be asked in this forum:
1) Whatever happens at interview, i have observed that there has been at least one question about op-amps and especially "virtual ground"....It was at cosmic circuits interview that i discovered the answer rather we came to a conclusion..So guys post what virtual ground is with the required mathematical proof and justification..
2) Another question which quite took me by surprise ... Well there are many ways to convert a latch to a flop.. but can a flop be converted to latch??If so how? if not why?

Hi guys, trivia again but this time i rephrased an interview question
ReplyDeleteLet me try the 2nd Q:
ReplyDeleteMy idea of a latch is, when the enable (or CLK) is high (or low based on which level the latch works), the output changes simultaneously in accordance with input.
Whereas in a flop, the input is captured on one level and output changes on the other level, thus ruling out instantaneous change of output with enable/clk signal.
Ofcourse, flop in itself is made of two latches in most cases, so a flop can be modified as two latches with opposite type of level triggering, if that cheeky answer is what the interviewer expects!
