Filter Frames of a Noisy Sine Wave Signal using Testbench Generator

This example shows how to use the Streaming Testbench Generator app to generate DSP algorithm testbenches. The DSP algorithm generated in this example is similar to the algorithm in the Filter Frames of a Noisy Sine Wave Signal in MATLAB example. That example filters a noisy sine wave signal using a FIR lowpass filter and displays the power spectrum using a spectrum analyzer.
