What is mean by high pass filter and low pass filter?

What is mean by high pass filter and low pass filter?
Where we use these filters? what is the basic difference in between them?

Hi,

Have a look here: http://en.wikipedia.org/wiki/High-pass_filter
http://en.wikipedia.org/wiki/Low-pass_filter
http://crca.ucsd.edu/~msp/techniques/v0.11/book-html/node129.html
or else follow any standard book on these in DSP or Circuit theory...

All type of filters links are here. Do a comparative study. It'll be easy for understanding.

Both filters are used for filtering the frequency . high pass filter passes frequency above a particular rage to infinity and low pass filter passes frequency between zero to a finite value .

A low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency.

A high-pass filter (HPF) is an electronic filter that passes high-frequency signals but attenuates (reduces the amplitude of) signals with frequencies lower than the cutoff frequency.

Filters are used to perform signal processing functions, specifically to remove unwanted frequency components from the signal.
