Flashcards

What does MIC1 do?

The MIC1 converts sound waves from your voice into a fluctuating electrical signal.

What's the role of capacitor C1?

C1 acts as a filter, allowing only the fluctuating signal from MIC1 to pass through, while blocking any DC component. This signal is then used to bias the transistor Q1.
