DSP stands for digital signal processor. It is a type of microcontroller. DSP are use for measuring, filtering and/or compress digital or analogue signal. Signal processing means analysis and manipulation of signal. Signal processing is done to obtained clear and pure signal. Signal processing is done via computer or Application Specific Integrated Circuits (ASCIs), Field Programmable Gate Array (FPGA) or Digital Signal Processor (DSP). DSP are useful in oscilloscope, barcode scanner, mobile phone, printers etc. DSP are fast and use for real time applications. DSP uses Harvard architecture, pipelining, replication, on chip memory/cache etc. DSP is capable of doing millions of floating point operation per second. The analogue signal go into antialiasing filter. Antialiasing filter will remove low frequency signal from high frequency signal. Then the filtered signal go to sample and hold device. There is a capacitor and a switch which turn on and off and sampling is occurred. Both input and output of DSP is in digital form. Sampling is done at the input of DSP and the analogue to digital converter converts analogue signal to digital. Then DSP measure, filter and/or compress digital or analogue signal. After that output of DSP is in digital form so reconstruction is needed digital to analogue converter converts digital signal into analogue.

4. • The analogue signal go into antialiasing filter.
• Antialiasing filter will remove low frequency signal from
high frequency signal.
• Then the filtered signal go to sample and hold device.
• There is a capacitor and a switch which turn on and off
and sampling is occurred.
• Both input and output of DSP is in digital form.
• Sampling is done at the input of DSP and the analogue
to digital converter converts analogue signal to digital.
• Then DSP measure, filter and/or compress digital or
analogue signal.
• After that output of DSP is in digital form so
reconstruction is needed digital to analogue converter
converts digital signal into analogue.
