WebSimple continuous wave radar devices without frequency modulation have the disadvantage that it cannot determine target range because it lacks the timing mark necessary to allow the system to time accurately the transmit and receive cycle and to convert this into range. In pulse modulation, the signal to be transmitted is in the formation of pulses. It is of two types which are Analog Pulse Modulation and Digital Pulse Modulation. Analog Pulse Modulation is of three types which are PAM, PWM, and PPM. Digital modulation is of two types: 1. Pulse Code Modulation 2. Delta … See more A continuous-wave is a type of wave which has a fixed frequency and amplitude. In continuous-wave modulation, continuous signals are formed after modulation. This type of modulation requires very less … See more PAM is a type of analog modulation technique.
