Applies an adaptive FIR filter to filter the input signal using a least-mean-square (LMS) adaptive filter algorithm.

This VI applies a FIR filter in which a LMS adaptive algorithm updates the coefficients to optimize the filter's response to LMS input1, which is the reference signal.

	LMS input0 is the data stream to filter.
	LMS input1 specifies the reference signal.
	filter order sets the length of the LMS filter.
	convergence factor is the weight vector convergence, which determines the speed of convergence.
	LMS output is the filtered signal.
