+ * @defgroup SignalConvergence Signal Convergence Example
+ *
+ * \par Description:
+ * \par
+ * Demonstrates the ability of an adaptive filter to "learn" the transfer function of
+ * a FIR lowpass filter using the Normalized LMS Filter, Finite Impulse
+ * Response (FIR) Filter, and Basic Math Functions.
+ *
+ * \par Algorithm:
+ * \par
+ * The figure below illustrates the signal flow in this example. Uniformly distributed white
+ * noise is passed through an FIR lowpass filter. The output of the FIR filter serves as the
+ * reference input of the adaptive filter (normalized LMS filter). The white noise is input
+ * to the adaptive filter. The adaptive filter learns the transfer function of the FIR filter.
+ * The filter outputs two signals: (1) the output of the internal adaptive FIR filter, and
+ * (2) the error signal which is the difference between the adaptive filter and the reference
+ * output of the FIR filter. Over time as the adaptive filter learns the transfer function
+ * of the FIR filter, the first output approaches the reference output of the FIR filter,
+ * and the error signal approaches zero.
+ * \par
+ * The adaptive filter converges properly even if the input signal has a large dynamic
+ * range (i.e., varies from small to large values). The coefficients of the adaptive filter
+ * are initially zero, and then converge over 1536 samples. The internal function test_signal_converge()
+ * implements the stopping condition. The function checks if all of the values of the error signal have a
+ * magnitude below a threshold DELTA.
