Component 1
Revise: Electronic Systems, Inputs and OutputsConsider an alarm designed to sound when light falls on a sensor. Its input is a light-sensing unit, its processing stage is a transducer driver, and its output is a buzzer. For a fan that switches on when a room becomes too warm, the corresponding blocks are a temperature-sensing unit, a transducer driver and a motor.
- Revise: Electronic Switching, Amplification and Timing
A circuit that allows a small control signal to operate an output transducer requiring a larger current.
