... Introduction to Telecommunications, Winter 2000 Lecture-22 Digital Transmission Digital Transmission of Analog Data (Baseband Transmission): • Analog voice data must be translated into a series ... domain. To get back the original analog signal we have to convert back the sampled signal to its unique analog form. We could do it if we have taken enough samples of the original signal in ... an analog signal is converted to its digital form. • To obtain either form of pulse modulation we start with sampling. Sampling is the process of taking samples (amplitude) of an analog signal...
