Digital signal processing ppt

Detection theory Discrete signal Estimation theory Nyquist—Shannon sampling theorem. Wikibooks has a book on the topic of: The output of a linear digital filter to any given input may be calculated by convolving the input signal with the impulse response. In DSP, engineers usually study digital signals in one of the following domains:

Frequency domain analysis is also called spectrum- or spectral analysis. There are various ways to characterize filters; for example:. This emphasizes the harmonic structure of the original spectrum.

If necessary converting the digital information back to analog signal. This is essentially no different from any other data processing, except DSP mathematical techniques such as signql FFT are used, and the sampled data is usually assumed to be uniformly sampled in time or space.

This article needs additional citations for verification.

A filter can be represented proessing a block diagramwhich can then be used to derive a sample processing algorithm to implement the filter with hardware instructions. Flexibility Reproducibility Reliability Complexity. But often it is another quantized signal that is converted back to analog form by a digital-to-analog converter DAC.

Also a growing number of DSP applications are now being implemented on embedded systems using powerful PCs with multi-core processors. Numerical methods require a quantized signal, such as those produced by an ADC. The signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency.

There are some commonly-used frequency domain transformations. Fundamentals of Digital Signal Processing.

Digital signal processing - Wikipedia

Introduction Use of multimedia in personal computers Requirement of more disk space Also telephone system requires compression Topics. Quantization means each amplitude measurement is approximated by a value from a finite set. Share buttons are a little bit lower. These often process data using fixed-point arithmetic, though some more powerful versions use floating point. The engineer can study the spectrum to determine which frequencies are present in the input signal and which are missing.

The Z-transform provides a tool for analyzing stability issues of digital IIR filters.
