What is the difference between the convolution and multiplication?
d) Convolution is a multiplication of added signals. Explanation: Convolution is defined as weighted superposition of time shifted responses where the whole of the signals is taken into account. But multiplication leads to loss of those signals which are after the limits.
What is convolution of polynomials?
Summary: If we treat digital sequences as coefficients of polynomials, then their convolution is nothing but the product of corresponding polynomials. A note on convergence: In general, convergence is a nonissue for finite sequences.
Why is convolution not multiplication?
Convolution, for discrete-time sequences, is equivalent to polynomial multiplication which is not the same as the term-by-term multiplication. Convolution also requires a lot more calculation: typically N2 multiplications for sequences of length N instead of the N multiplications of the term-by-term multiplication.
What is the meaning of multiplying polynomials?
Polynomial multiplication is a process for multiplying together two or more polynomials. We can perform polynomial multiplication by applying the distributive property to the multiplication of polynomials.
