## Principles of Digital Signal Processing Notes

EC 6502 Principles of Digital Signal Processing Notes for free download. DSP – Digital Signal Processing. It is defined as changing or analyzing information which is measured as discrete time sequences. Signal is a physical quantity that varies with respect to time , space or any other independent variable. (Or) It is a mathematical representation of the system

### Energy and power signal

A signal is said to be energy signal if it have finite energy and zero power. A signal is said to be power signal if it have infinite energy and finite power. If the above two conditions are not satisfied then the signal is said to be neither energy nor power signal.

### Analog signal Principles of Digital Signal Processing Notes

The analog signal is a continuous function of independent variables. The analog Signal is defined for every instant of independent variable and so magnitude of Independent variable is continuous in the specified range. Here both the independent Variable and magnitude are continuous.

### Periodic and non periodic discrete time signals

If the discrete time signal repeated after equal samples of time then it is called periodic signal. When the discrete time signal x[n] satisfies the condition x [n+N]=x(n), then it is called periodic signal with fundamental period N samples. If x(n) * x(n+N) then it is called non periodic signals.

### Classification of discrete time signals.

The types of discrete time signals are

- Energy and power signals
- Periodic and A periodic signals
- Symmetric (Even) and Ant symmetric (Odd) signals
