# PSPICE SYNTAX & COMMAND SUMMARY

### .FOUR - Fourier Analysis

General Format :
.FOUR |frequency value| |output variable|
A Fourier analysis is performed and the |output variable| signal
transient analysis results are decomposed into its Fourier components
with the fundamental frequency given by |frequency value|.
Example :
.TRAN 1u 1m
.FOUR 10K V(5) V(7)
The results of the transient analysis run for the voltages on nodes
5 and 7 are decomposed into its Fourier components with 10kHz as the
fundamental frequency.
