Periodic convolution is valid for discrete Fourier transform. To calculate periodic convolution all the samples must be real. Periodic or circular convolution is also called as fast convolution. If two sequences of length m, n respectively are convoluted using circular convolution then resulting sequence having max [m,n] samples so a convolutional integral. I was thinking to bypass this problem by introducing a costraint equation which solution of is just that integral. I'm not sure if I could use the Global equation tool or i better define a new independent variable and set the constraint by the new generated field equation (I used this trick other times)

Convolution: g*h is a function of time, and g*h = h*g - The convolution is one member of a transform pair g*h ↔ G(f) H(f) The Fourier transform of the convolution is the product of the two Fourier transforms! - This is the Convolution Theorem. Worked out Problems: Example 1: the input and impulse response to the system are given b You can actually solve this problem using convolution. However, the sample solution provided by SOA did not use convolution. But that solution is long and is no more efficient than doing convolution. So convolution is at least as good as the sample solution. However, the approach in the sample solution is worth knowing The required solution can then be found by inversion. Example.
