Using MATLAB compute the convolution of the following signals: a) x (n) = {1,2,4}, h (n) ={1,1,1,1,1} Also, plot the convolution.

Design a-full subtractor with two multiplexers (MUXS) S(xy.2) = E( ...) , C(x.y.2) = E( ...). Connect the variable z to the data inputs. Connect the variables x and y to the selection inputs.

Design a circuit using a Multiplexer, (((USING A MULTIPLEXER NOT A DECODER))) that has two inputs X, and S, where X represents an 8-bit BCD number,S is a sign bit. The circuit has one output Y, which is the Binary representation of thesigned-magnitude BCD number. A negative output is represented in the Binary 2’scomplement form.
