Q. What do you mean by Continuous signals?
Continuous signals are described by time functionswhich are defined for all values of t (a continuous variable). Commercial broadcast systems, analog computers, and various control and instrumentation systems process continuous signals. The information processed in analog systems is contained in the time function which defines the signal. Analog systems are often thought of as performing signal processing in the frequency domain.
Why is an armature winding in d.c machine called closed winding.
