WebCreate a flowgraph like the one in the video or like the screenshot below. Add two more taps with sliders to the filter in the flowgraph. Run the flowgraph and adjust the sliders to try to create a low pass filter with the stop band least 20 dB below the pass band and with a filter (pass band) bandwidth close to half the visible bandwidth.
