To view the mid, and low frequency output sine waves, perform the following steps:
  1. Cycle the sine wave sequential circuit by pressing the GPIO_SW_E push button as shown in the following figure.

  2. Click Run Trigger Immediately again to see the new sine selected sine wave. You should see the mid frequency as shown in the following figure. The sel signal also changed from 0 to 1 as expected.

  3. Repeat step 1 and 2 to view other sine wave outputs.

    Note: As you sequence through the sine wave selections, you can see that the LEDs do not light up in the expected order. You debug this in the next section of this tutorial. For now, verify for each LED selection that the correct sine wave displays.
    Note: The signals in the Waveform window are re-arranged in the previous three figures.
