Can we add two signals?

Signal addition—Two signals x(t) and y(t) are added to obtain their sum z(t). An adder is used. Constant multiplication—A signal x(t) is multiplied by a constant α. A constant multiplier is used.

How do you add two discrete signals?

In order to simultaneously shift and add two discrete time signals, we can only make use of indices of x1 and x2 which can only be positive integers. So, for y[n] = x1[n-2]+x2[n], n should always be greater than 3.

How do you add two signals in Matlab?

x1 = imresize(x1, newsize); x2 = imresize(x2, newsize);
