Digital Design Engineer Interview Questions and Answers for Freshers

I have studied digital design, setup hold time is the time data must be stable before and after the clock edge, fixing it involves adjusting the clock or data path, setup time is more critical, a circuit with fewer stages is better for delay and power.

A 2:1 mux can be used to design and gate.

• A 2:1 mux has two inputs and one output.

• The output is selected based on the value of the select input.

• To design an AND gate using a 2:1 mux, connect one input to the select input and the other input to the data input.

• Connect the output of the mux to the AND gate output.

• The truth table for the AND gate can be derived from the truth table of the 2:1 mux.

Mux is used to select one of several input signals and forward the selected input to the output.

• Multiplexers are used in digital circuits to select one of several input signals and forward the selected input to the output.

• Mux is used in data transmission systems to combine multiple data streams into a single stream.

• Mux is used in memory systems to select a particular memory location for read or write operations.

• Mux is used in microprocessors to select a particular register or...read more
