A sinusoidal carrier voltage of frequency \(1\ \text{MHz}\) and amplitude \(100\ \text{Volts}\) is amplitude modulated by a sinusoidal voltage of frequency \(5\ \text{kHz}\) producing \(50\%\) modulation. The frequency and amplitude of the lower and upper sideband terms will be:

An AM transmitter is coupled to an aerial. The input current is found to be \(5\ \text{A}\). With modulation, the current value increases to \(5.9\ \text{A}\). The depth of modulation is:
