ECT 350 ELECTRONIC COMMUNICATIONS FUNDAMENTAL COMMUNICATIONS ANALYSIS PROJECT 2 1. What is frequency? It is the number of times a particular phenomenon occurs in a given period of time. 2. What is wavelength? It is the distance used or occupied by one cycle of a wave, and is usually expressed in meters or feet 3. Calculate the frequency of signals with wavelengths of 40 m, 5 m, and 8 cm. f = c λ a) 3 x 10 8 /40 = 7.5MHz b) 3 x 10 8 /5 = 60MHz c) 3 x 10 8 /.08 = 3750MHz 4. A commonly used frequency range is 902 to 928 MHz. Compute the bandwidth of this frequency range? BW = f 2 – f 1 = 928 MHz – 902 MHz = 26 MHz
