    Time Invariance of System with x(t) and y(t) Equations

    The first question has T and alpha, that's what I meant by two terms. It's fine, I figured it out

    Time Invariance of System with x(t) and y(t) Equations

    The way I was thought is that for y1(t) your replace x(t) with x1(t), for y2(t) you replace x(t) with x2(t) which then equals x1(t-t0). Then if y2(t)= y1(t-t0). It's time invariant. My issue is doing that with two terms or a negative t

    Time Invariance of System with x(t) and y(t) Equations

    Okay so the question looks like this Determine whether the system with input x(t) and output y(t) defined by each of the following equations is time invariant: (c) y(t) =∫t+1t x(τ−α)dt where α is a constant; (e) y(t) = x(−t); There are more sub-questions but I was able to solve them. The reason...

    Identifying time and/or amplitude transformations

    I guess I know the parts that are time shift and amplitude scaling. I just don't get what the question is asking. Do i write the parts and label them? I slightly get the first part of the question. It's the "chose the transformation such that" part that's confusing me. I don't need answers or...

    Identifying time and/or amplitude transformations

    So the question looks like this: Identify the time and/or amplitude transformations that must be applied to the signal x(t) in order to obtain each of the signal specified below. Choose the transformations such that time shifting precedes time scaling and amplitude scaling precedes amplitude...
