Digital Signal Processors (DSP) Video Lecture - Embedded Systems (Web) - Computer Science Engineering (CSE)

the analog signal go into anti-aliasing
filter anti-aliasing 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 analog to digital converter converts
analog signal to digital and DSP measure
filter and slash or compressed digital
or analog signal after that output of
DSP is in digital form so reconstruction
is needed digital to analog converter
converts digital signal into analog
digital signal processors DSP DSP stands
for digital signal processor it is a
type of microcontroller DSP are used for
measuring filtering and /or compressed
digital or analog signal signal
processing means analysis and
manipulation of signal signal processing
is done to obtain clear and pure signal
signal processing is done via computer
or application specific integrated
circuits a size 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 used 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
