- | Waveform generator AWG1 should be set up as a triangle wave with a 4 Volt amplitude and 0 V offset and a frequency of 5 KHz. Set the horizontal and vertical scales of the scope to display at least one complete cycle of the input triangle waveform. Turn on the power supplies only after double checking your circuit connections. | + | Waveform generator AWG1 should be set up as a triangle wave with a 8 Volt amplitude and 0 V offset and a frequency of 5 KHz.

To start, set the scope trigger source to Channel 1, rising edge, with the level set to 0 V. You should see the rising edge of the triangle wave on channel 1 centered on the 0 time point along the horizontal axis. The rising edge of the digital output of the second inverter on channel 2 should occur at different times along the horizontal axis depending on the setting of the potentiometer, | To start, set the scope trigger source to Channel 1, rising edge, with the level set to 0 V.
