1.	Linear devices are used in __________(a) high level AM modulator(b) low level AM modulator(c) high level FM modulator(d) low level FM modulatorThis question was posed to me in a national level competition.I'd like to ask this question from Demodulation of SSB-SC in division SSB Modulation of Analog Communications
Answer» Correct choice is (b) low level AM modulator Best explanation: In low-level modulation, the GENERATION of amplitude modulated SIGNAL takes place at low power levels. The generated AM signal is then AMPLIFIED using a chain of LINEAR amplifiers, which are required to avoid waveform distortion. Thus, linear devices are used in low level amplitude modulated SYSTEM.
