How do I create a 0-3V TTL waveform at 20 Hz in Capture (Pspice)?

[snoggerT]

Can someone explain to me how to create a 0-3V TTL waveform at 20 Hz in Capture (Pspice)?

- edit: Figured out how to adjust the pot, but still can't figure out the TTL waveform.

TTL isn't a 0~3V waveform. it's a specification for range of acceptable output voltages and acceptable input voltages, etc.

and you could find more info via google.

Creating a 0-3V TTL waveform at 20 Hz in Capture (Pspice) can be achieved by using a combination of components and settings within the software. To begin, you will need to use a pulse generator component and set the frequency to 20 Hz. This will provide the base frequency for the waveform.

Next, you will need to use a voltage source component and set the voltage to 3V. This will provide the high voltage level for the TTL waveform. Then, you will need to use a voltage-controlled switch component and connect it to the pulse generator and voltage source. This will allow the pulse generator to control the switching of the voltage source.

To create the low voltage level for the TTL waveform, you can use a ground component and connect it to the other end of the voltage-controlled switch. This will create a complete circuit for the waveform.

Finally, to adjust the TTL waveform to have a 0V low level and a 3V high level, you can use a potentiometer component and connect it to the voltage source and ground. By adjusting the potentiometer, you can control the voltage level and create the desired 0-3V TTL waveform.

It is important to note that the specific components and settings may vary depending on the version of Pspice you are using. I recommend consulting the software's user manual or online tutorials for more specific instructions.
