An amplitude modulation spectrum is represented as:
fc = Carrier Frequency
fm = Signal frequency
fc + fm = Upper Sideband
fc - fm = Lower Sideband
Analysis:
Given fc = 40 kHz and fm = 5 kHz
The upper and lower sidebands after Amplitude modulation will be:
Upper Sideband = fc + fm = 40 + 5 kHz = 45 kHz
Lower Sideband = fc - fm = 40 - 5 kHz = 35 kHz
