Design Digital Interview Questions

820 design digital interview questions shared by candidates

Round 1:- Logic Families, Mux, Demux, In CMOS circuits, which among tphl and tplh is longer? And why? Divide-by-3 counter, Round 2:- (after a wait of the futile 4 hours) Significance of 'reset' signal in digital circuits Given a step input to a low pass filter, high pass filter and band pass filter respectively, what do you expect the output to look like? Dissimilate a square wave into its harmonics (this question because I had mentioned signal processing projects in my resume) Now a days we have a large number of cells in logic blocks? What do you think is the approach to detect an error in such a case?
