Detailed Description

Vector IIR Block Control Class

The Vector IIR Block is an RFNoC block that implements an infinite impulse filter with a variable length delay line. The transfer function is defined as follows:

               beta

H(z) = ---------------------— 1 - alpha * z ^ -delay

where

beta is the feedforward tap
alpha is the feedback tap
delay (a.k.a. vector length) is the feedback tap delay

Member Function Documentation

◆ get_alpha()

virtual double uhd::rfnoc::vector_iir_block_control::get_alpha ( const size_t chan ) const

pure virtual

Return the feedback tap value

Returns the feedback tap value for channel chan of the IIR filter.

Parameters

chan	The channel to retrieve the feedback tap value from

◆ set_alpha()

virtual void uhd::rfnoc::vector_iir_block_control::set_alpha	(	const double	alpha,
		const size_t	chan
	)

pure virtual

Set the feedback tap value

Sets the feedback tap value for channel chan of the IIR filter.

Parameters

alpha	The feedback tap value for the filter
chan	The channel to apply the feedback tap value to

◆ set_beta()

virtual void uhd::rfnoc::vector_iir_block_control::set_beta	(	const double	beta,
