Unformatted text preview: h ( t ) = δ ( t )-e-2 t u ( t ) (a) This system will act as a ±lter, i.e., blocking high frequency signal components (low-pass ±lter), passing signals in a certain freqency band only (band-pass), or blocling low frequency compo-nents (high-pass). Determine what type of ±lter this system is by computing and sketching its magnitude response. (b) Determine the output y ( t ) if x ( t ) = 2 cos(10 πt + π/ 4) is applied as input. (c) Determine the Fourier Transform X ( ω ) of input x ( t ) if y ( t ) = exp(-t ) u ( t ) is received at the output. 1...
