Detailed Description

Moving Average Block Control Class

The Moving Average block is an RFNoC block that computes the running average of an input data stream. The output is the sum of the last SUM_LEN samples divided by DIVISOR which may or may not be equal to SUM_LEN. For example, if SUM_LEN is set to 10 and DIVISOR is set to 10, the block will return a sample that is the average of the last 10 samples. If SUM_LEN is set to 10 and DIVISOR is set to 1, the block will return a sample that is equal to the sum of the last 10 samples.

◆ get_divisor()

virtual uint32_t uhd::rfnoc::moving_average_block_control::get_divisor ( ) const
pure virtual

Return the current divisor

Returns
The amount to divide the sum by

◆ get_sum_len()

virtual uint8_t uhd::rfnoc::moving_average_block_control::get_sum_len ( ) const
pure virtual

Return the current sum length

Returns
The number of samples to sum

◆ set_divisor()

virtual void uhd::rfnoc::moving_average_block_control::set_divisor ( const uint32_t  divisor)
pure virtual

Set the divisor

Parameters
divisorThe amount to divide the sum by

◆ set_sum_len()

virtual void uhd::rfnoc::moving_average_block_control::set_sum_len ( const uint8_t  sum_len)
pure virtual

Set the Sum Length

Changing the sum length will clear the history and reset the accumulated sum to 0.

Parameters
sum_lenThe number of samples to sum
