These outputs combine both audio and vid...The RF at the output of the leftmost bandpass filter, BPF1, still has a spectrum that is much broader than that of the desired communication signal. For example, in 3G radio the communication channel is \(5\text{ MHz}\) wide but the first BPF could be \(50\text{ MHz}\) wide and the RF could be \(1\text{ GHz}\) or \(2\text{ GHz}\).Fading refers to the variation of the received signal with time or when the position of transmit or receive antennas is changed. The variation in signal strength is much greater than would be expected from changes in path. Figure \(\PageIndex{5}\): Fast and slow fading: (a) in time as a radio and obstructions move; and (b) in distance. length.RF signal wavelength is small in comparison to the length of the cable, thus multiple cycles of the signal simultaneously propagate through the cable. As a result, the amplitude of an RF signal varies (since it is a wave), while it is constant for a DC signal. Compensation for signal degradation due to reflection and power lossesAir is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light.

RF signals operate within a specific frequency range, and the frequency determines various aspects of the signal, such as its ability to penetrate obstacles and its data-carrying capacity. The amplitude of an RF signal represents its strength or intensity. It is the measure of the maximum deviation of the signal from its average value.RF modulation classification and RF fingerprint recognition have been recently explored29,30 as well. The goal of modulation classification is to identify and classify a given RF signal to a known modulation type whereas RF fingerprint recognition is a method to identify the annunciator or the transmitting circuit.
