The signal generator determines the frequency that the transmitter operates on throughout the transmission process.

Power amplification is the final stage of the radio frequency signal transmission process. The power amplifier strengthens the radio frequency to enable long distance transmission through the channel. Transmission of the radio frequency over long distances requires strong signals of since it is difficult to transmit weak signals over long distances.

The frequency of the detected signal is less than the frequency of the message signal. The reduction in the measurement of the stimulation frequency and the message signal frequency is because of errors in detecting the signal.

The figure represents a single frequency wave implying that a single sine wave modulation signal is used. The evaluation of the upper sideband is done by use of the following formula. upper Side Band=fcarrier frequency+fmessage frequency. On the other hand, the lower Side frequency has its calculation using the formula. carrier frequency-message frequency. This implies that:

Mathematical formulation method is used in locating the lower sideband frequency signal. Quadratic modulation of amplitude mathematical form is used to represent different sidebands in a radio frequency as shown below.

b. In the frequency modulating signals (FM), the carrier combines with the modulating signal hence causing the frequency of the resulting to vary with respect to the variation of the modulating signal’s instantaneous amplitude. The frequency modulation signals go through the following stages: speech amplification, modulation, oscillation, frequency multiplication and power amplification.

The microphone receives the audio signals from the source and converts them to electrical signals.
