An amplitude modulator has output (in Volts)
s(t) = A cos(400πt) + B cos(360πt) + B cos(440πt).
The carrier power normalized to 1Ω resistance is 50 Watts.
The ratio of the total sideband power to the total power is 1/9.
The value of B (in Volts, rounded off to two decimal places) is
s(t) = A cos(400πt) + B cos(360πt) + B cos(440πt).
The carrier power normalized to 1Ω resistance is 50 Watts.
The ratio of the total sideband power to the total power is 1/9.
