the question is "verify the convolution theorem of Fourier transform for signals x(t)=Π(t)and y(t)=Λ(t)numerically,once by determining the convolution directly and once by using the Fourier transform of the two signals."
x(t)->square signals y(t)->triangular signals
thanks

convolution of two signals is nothing but the simple multiplication of the fourier transform of the signal. Let me describe you in steps for ur easy understanding.
1.Find the Fourier transform using x=fft(m) 2.Find fft of the 2 signals using fft function 3.multiply the two signals 3.take ifft of the multiplied output using ifft function 4. compare the outputs u ll find them same.
