AIonSi Interview Questions and Answers

Q1. What is Metastability?
Ans. 
Metastability is a phenomenon in digital circuits where a flip-flop enters an undefined state due to timing violations.
• Occurs when a flip-flop samples an input signal at a time when it is transitioning between logic levels

• Can lead to unpredictable output and potentially cause system failures

• Can be mitigated by using synchronization techniques such as double or triple flopping

• Common in high-speed digital designs

Q2. Design a 8:1 mux using 3 to 8 decoder
Ans. 
Use a 3 to 8 decoder to design an 8:1 mux.
• Connect the inputs of the 3 to 8 decoder to the select lines of the mux.

• Use the outputs of the decoder as the control signals for the mux.

• Connect the data inputs of the mux to the corresponding outputs of the decoder.
