What is Signal and Advantage of DSP | DSP Lec-1

• What is Signal?

Ans: A signal is defined as any physical quantity that various with time, space or any other variable or variable mathematically.

We can describe a signal as:

S₁(t) = st,

Where t= independent variable

S₂ (x, y) = a_x + by²

Digital signal: A discrete-time signal will have values at intervals along the

Time axis-

Basic element of a digital signal processing system:

2Write down the Advantage of Digital Signal processing (DSP) over Analog signal processing:

1. .     Digital Signal processing allows flexibility in reconfiguring the operation by changing program.
2. .     DSP provides much better control of accuracy requirements.
3. .     Digital Signals are easily stored magnetic media. ex: tape on disc
4. . DSP is cheaper than its analog counter part.
