# How do you get square waves in pspice?

## How do you get square waves in pspice?

You use either a Pulse or PWL (piecewise linear) wave form option on your voltage or current source….If you mean in OrCAD Capture with PSPICE simulation enabled, then do the following:

1. select Place Part (P for shortcut),
2. type VPULSE in the Part Search field, then.
3. VPULSE should show up in the SOURCE. OLB library.

What is ton in LTspice?

The Ton will be half that for a 50% duty cycle, or 0.000005s. The rise and fall times may be left at zero. If you wanted a 20% duty cycle the Ton time would be 0.000002.

### How do you make a triangular wave in LTspice?

LTspice has a built in triangle wave function, although it may not seem that way. Select ‘Voltage Source’, then ‘Advanced’ and select ‘Pulse’. By using a rise and fall time equal to 1/2 of your period of your pulse function, you are creating a triangle wave.

What is SFFM in LTspice?

SFFM. The SFFM (Single Frequency FM) type of source has these parameters: DC offset the DC component of the sine wave. Amplitude the AC value of the sine wave. Carrier Freq is the carrier frequency.

What is voltage pulse?

A pulse is a burst of current, voltage, or electromagnetic-field energy. In digital circuits, pulses can make the voltage either more positive or more negative. Usually, the more positive voltage is called the high state and the more negative voltage is called the low state.

## What is von in LTspice?

Voltage Source. Symbol Names: VOLTAGE, BATTERY.

What is pulse in LTspice?

LTspice® simulation software has a built-in pulse, sine, exponential, single frequency FM and an arbitrary piece-wise linear functions available in the source component editor. PULSE fuction is often used in transient circuit simulation where we want the source to behave like a square wave.

### What is .OP in LTspice?

op) method in LTspice. The DC operating point analysis calculates the DC voltage and current of each node in the steady state of the electronic circuit.
