SUMMARY

The discussion focuses on implementing the convolution of three functions using the Fast Fourier Transform (FFT) in MATLAB. The user, Kamru, seeks guidance on the MATLAB implementation process. A key point highlighted is the use of the built-in conv(u,v) function for convolution, where vectors must be represented in complex form, utilizing "j" for imaginary numbers instead of "i".

PREREQUISITES
  • Familiarity with MATLAB programming environment
  • Understanding of Fast Fourier Transform (FFT) concepts
  • Knowledge of complex numbers and their representation in MATLAB
  • Basic understanding of convolution operations in signal processing
NEXT STEPS
  • Explore MATLAB's fft function for efficient convolution
  • Research advanced convolution techniques using FFT in MATLAB
  • Learn about complex number operations in MATLAB
  • Study the implications of convolution in signal processing
USEFUL FOR

This discussion is beneficial for MATLAB users, signal processing engineers, and anyone interested in implementing convolution operations using FFT in their projects.

Hi, I need help about the convolution of 3 functions as shown in

attached file via FFT. Specially I need help about the Matlab

implementation of whole process.

Thanks in Advance.


Regards
Kamru

In Matlab there is a conv(u,v) function where u and v are your vectors. I think you have to write the vectors in complex form (as in the form with imaginary numbers). Matlab uses "j" i think instead of "i"
