Digital communications and digital media are everywhere in our live and the signal processing of informations / data is more important than ever. Signal processing is the enabling technology for the generation, transformation, and interpretation of information. Analog and digital signal processing are everywhere. Signal processing is transforming and filtering of informations. You can do it in an analog way, like filtering and / or modulation the signal.

Digital communications and digital media are everywhere in our live and the signal processing of informations / data is more important than ever. Signal processing is the enabling technology for the generation, transformation, and interpretation of information. Analog and digital signal processing are everywhere. Signal processing is transforming and filtering of informations. You can do it in an analog way, like filtering and / or modulation the signal.

 

In the digital processing of analog signals proceeds you need three steps:

  • The analog signal is digitized, that means it is sampled and each sample are quantized to a number of bits. This process is the A/D conversion.
  • The digitized samples / data are processed by a digital signal processor (DSP).
  • The resulting output samples / data may be converted to an analog signal done by an analog reconstructor, this is the D/A conversion.

 

Digital signal processing applications are

  • Digital Waveform Generators
  • Digital Audio / Image Effects
  • Noise Reduction and
  • Signal Enhancement

 

A conversion to analog is necessary because the world is analog. 0 and 1 can not be processed from humans.
