You can process signals with many analog circuits. The advantage of Digital Signal Processing, is that once you have represented the signal in a digital form, you can use a computer program to perform much more complex operations on the signal than could be accomplished with an analog circuit. Such examples are noise cancellation and compression. With the recent advent of 'Digital TV', the stations can fit more information into a smaller 'bandwidth' through compression (much as you might ZIP a large file before emailing it), allowing for delivery of more content.

What is the expansion of Digital Signal Processing?
Digital Signal Processing
What are basic elements of digital signal processing?
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
What is the best signal processing either a analog signal processing?
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal

Difference between analog and digital signal processing?
we can do analog signal processing also but it is very expensive as comparing with digital signal processing that's why we generally choose the digital signal processing.DSP allows programmable operations.But we cannot do in ASP.

What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
What is advantage of digital signal processing?
Digital is always preferred over analog for the following reasonsAccuracyImmune to noiseEasy error detection and correctionThe same is true for digital signal processing too.
What is digital signal processing system?
DSP -Digital signal processing the word it self says it is process of analyzing the digital signal . The system which does this work of analysis is the digital signal processing system. In this system the raw analog signal(ex:human voice) which is time domain signal is fed to the pre aliasing filter which removes noise part of the signal and this fed to the sampling and quantization in which the real time analog signal is discretized and digitized . After this process this digitized signal is fed to the DSP processor to do the specific operation on the signal (ex: convolution , modulation etc.,) .This processed signal is fed to the D/A which converts the digital signal to the analog signal real time signal. after all explaining the process of signal processing. the stages between the sampling and D/A is the digital processing system.
