represented by a sequence of pulses by means of a line code ( baseband transmission), or by a limited set of continuously varying waveforms ( passband transmission), using a digital modulation method. the passband modulation and corresponding demodulation (also known as detection) is carried out by modem equipment
it may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream, for example, using pulse-code modulation (pcm) or more advanced source coding ( analog-to-digital conversion and data compression ) schemes. this source coding and decoding is carried out by codec equipment...
