Low level modulation examples

Examples of low level modulation are

a.) Square law diode modulation
b.) Switching modulation
c.) Frequency discrimination method
d.) Both a) and b)

Correct Answer: d) both a) and b)


In a Low level Amplitude Modulation system, modulation is done at lower power of carrier and modulating signal. Therefore the output power of modulation is low. So power amplifiers are required to boost the signal up to the desired power level. Examples of low level modulation are

i.) square law diode modulation
ii.) switching modulation
