This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.
 
As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

This filter is a convenience wrapper for an FIR Filter and a firdes taps generating function of high-pass type, i.e. calling firdes.high_pass().

Parameters

(R): Run-time adjustable

FIR Type (R)
Specify whether input/output is real or complex
Decimation
Decimation rate of filter, must be an integer, and cannot change in realtime.
Gain (R)
Scaling factor applied to output.
Sample Rate (R)
Input sample rate.
Cutoff Freq (R)
Cutoff frequency in Hz
Transition Width (R)
Transition width between stop-band and pass-band in Hz
Window (R)
Type of window to use
Beta (R)
The beta paramater only applies to the Kaiser window.
