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

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

 

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

  • The analog signal is digitized, that means it is sampled and each sample 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 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 by humans.
