NEED DSP?
In reality, most signals start out (and may very well end up) as an analog signal. However, to make use of digital signal processing, they are converted into a digital representation of the signal by sampling with an ADC (or they are returned to analog via a DAC). The sequence of samples is in the time or spatial domain. Algorithms can be used on the sequence to measure or filter it. The DSP is specifically designed for computational efficiency and throughput of data. A typical DSP application might include audio processing, image processing, or compression, as well as data processing, analysis, and control of industrial processes.
The dsPIC series integrates a DSP engine into the 16-bit PIC24 series of microcontrollers. Today, the dsPIC series consists of two families, the dsPIC30 and the dsPIC33 families.
