2. (a) Let \varphi(t) be the scaling function defined by varphi(t)= chi [0,1] .If h(t)= varphi(2021t). then find hat h (0) . (b) Let \varphi(t) = \delta(t) be the impulse function. Define hat g (w)= hat varphi ( w 2022 ) , then find the signal g(t) in terms of \delta(t) .
2. (a) Let y(t) be the scaling function defined by y(t) = X(0.1). If h(t) = 4(2021t), then find h(0). (b) Let y(t) = 8(t) be the impulse function. Define ĝ(w) = f(2022), then find the signal g(t) in terms of 8(t). =
