Q. What is Discrete signals?
Discrete signals, on the other hand, exist only at specific instances of time, and as such, their functional description is valid only for discrete-time intervals. Discrete signals are invariably a sequence of pulses in which the information is contained in the pulse characteristics and the relation amidst the pulses in the sequence during a specified time interval. Digital computers, pulsed-communication systems (modern telephone and radar), and microprocessor-based control systems utilize discrete signals. Digital systems process digits, i.e., pulse trains, in which the information is carried in the pulse sequence rather than the amplitude time characterization of the pulses. Digital systems are often thought of as performing signal processing in the time domain. Because of the advantages of economy in time, low power consumption, accuracy, and reliability, digital communication systems are increasingly used for transmitting information.
