Continuous And Discrete Time Signal
A signal x(t) is a continuous-time signal if t is a continuous variable. If t is a discrete variable, that is, x(t) is defined at discrete times, then x(t) is a discrete-time signal.a discrete-time signal is often identified asa sequence of numbers, denoted by {x,) or x[n], where n = integer
Analog And Digital Signal
A signal x(t) is a continuous-time signal if t is a continuous variable. If t is a discrete variable, that is, x(t) is defined at discrete times, then x(t) is a discrete-time signal.a discrete-time signal is often identified asa sequence of numbers, denoted by {x,) or x[n], where n = integer
Analog And Digital Signal
- If a continuous-time signal x(l) can take on any value in the continuous interval (a, b),where a may be - 03 and b may be + m, then the continuous-time signal x(t) is called analog signal.
- If a discrete-time signal x[n] can take on only a finite number of distinct values, then we call this signal a digital signal.
