The Correct Option is C

Solution and Explanation

Concept: Oscillators generate periodic waveforms and are used where repetitive signals are required.

Step 1:
Signal generators use oscillators to produce test signals.

Step 2:
Radio transmitters use oscillators to generate carrier waves.

Step 3:
Digital clocks use oscillators to produce timing pulses.

Step 4:
A rectifier does not generate oscillations. It converts AC into DC. Therefore, the option which is not an oscillator application is: \[ \boxed{\text{Rectifier}} \]
