Fast Fourier Transform (FFT)

 

 


Property

Description

Units

Default

Range/Type

FFTL

FFT length

None

1024

[1, Inf)/Integer

RIN

Input impedance

Ohm

Inf

(0, Inf]/Real

ROUT

Output impedance

Ohm

0

[0, Inf)/Real

Ports

Input

Input signal (complex)

Output

Output signal (complex)


 

Notes

1. This model performs FFT on the incoming signal. If “FFTL” is not a power of 2, it will be set to the integer next power of 2 value greater than FFTL.

Netlist Form

FFT:NAME n1 n2 fftl=val [Rin=val] [Rout=val]

Netlist Example

FFT:1 1 2 fftl = 2048
