Detailed Description

Buffer class for parametrized low-pass filter.

This class extends the CBuffer< double > class by adding several variables that define a symmetric-odd FIR low-pass filter windowed by Peaked Cosine window function. This class can be used to compare filters without comparing their buffer contents.

Member Function Documentation

bool avir::CFltBuffer::operator==

(

const CFltBuffer &

b2

)

const

Parameters

b2	Filter buffer to compare *this object to.

Returns

Operator returns "true" if both filters have same parameters.

Member Data Documentation

double avir::CFltBuffer::Alpha

Peaked Cosine window function Alpha parameter.

double avir::CFltBuffer::DCGain

DC gain applied to the filter.

double avir::CFltBuffer::Freq

Low-pass filter's corner frequency.

double avir::CFltBuffer::Len2

Half-length (non-truncated) of low-pass filters, in samples (taps).
