WebAmplitude modulation basically shifts the center of the audio range to a fixed RF station. Every station has their own frequency and the receiver can choose which station to select and extract the audio. In the frequency domain, the figure below explains the action performed by modulating and demodulating. WebDefinition. RF circuit design is a discipline that focuses on the creation of circuits that operate in radio frequencies. RF stands for Radio Frequency, which represents the oscillation rate of electromagnetic waves. Frequency is measured in Hertz (Hz), which is equal to the number of oscillation cycles per second (1/s).
