Question 1
What is the purpose of coupling capacitors in amplifier circuits?
- To amplify DC signals
- To connect different stages
- To block all signals
💡 Hint: Consider a gate that only lets certain signals through.
Question 2
True or False: A higher cutoff frequency will allow lower frequencies to pass through an amplifier.
- True
- False
💡 Hint: Think of it like a filter that only allows bigger waves and blocks smaller ones.
