Convolution The convolution of two functions is the overlap of the two functions as one function is passed over the second. The convolution symbol is. The convolution of h(t) and g(t) is defined mathematically as The above eq - n is depicted for rectangular shaped h(t)and g(t) functions in this animation g(t) f(t) Imaginary numbers are those which result from calculations involving the square root of-1 Imaginary numbers are symbolized by i A complex number is one which has a real (RE)and an imaginary(IM)part. The real and imaginary parts of a complex number are orthogonal Two useful relations between complex numbers and exponentials are e"ix=cos(x)+isin(x) Ix =cos(x)-isin(x)Convolution The convolution of two functions is the overlap of the two functions as one function is passed over the second. The convolution symbol is . The convolution of h(t) and g(t) is defined mathematically as The above equation is depicted for rectangular shaped h(t) and g(t) functions in this animation. Imaginary Numbers Imaginary numbers are those which result from calculations involving the square root of -1. Imaginary numbers are symbolized by i. A complex number is one which has a real (RE) and an imaginary (IM) part. The real and imaginary parts of a complex number are orthogonal. Two useful relations between complex numbers and exponentials are e +ix = cos(x) +isin(x) and e -ix = cos(x) -isin(x)
