From where does the intelligence amplifier receive its signal?
A)Input transducer
B)Oscillator
C)Modulator
D)Cathode

Question

Quizplus · Accepted Answer

The intelligence amplifier receives its signal from an input transducer, which converts the input signal (e.g. sound waves, electrical signals) into an electrical signal that can be amplified by the amplifier. Oscillators generate a continuous signal, modulators vary the amplitude or frequency of a signal, and cathodes emit electrons in a vacuum tube. None of these components are responsible for providing the signal to be amplified.
