Unformatted text preview: 1 (i) y ( t ) = x ( t )-R t-∞ ( t-σ ) 2 σx ( σ ) dσ, t >-∞ (ii) y ( t ) = R ∞-∞ ( t-σ ) U ( σ-t ) x ( σ ) dσ, t ∈ (-∞ , ∞ ) . Which system is TV? Which one is NC? Write down the IRF h ( t,τ ) of systems (i) and (ii). 5. Find the impulse response function h ( t,τ ) of the systems with the follow-ing input-output descriptions: (i) y ( t ) = R t-∞ U ( σ ) x ( σ ) dσ,-∞ < t < ∞ (ii) y ( t ) = R ∞-∞ tU ( t-σ ) x ( σ ) dσ,-∞ < t < ∞ (iii) x ( t ) → [ S 1 ] → z ( t ) → [ S 2 ] → y ( t ) z ( t ) = e-t x ( t ) U ( t ); y ( t ) = Z t e-( t-σ ) z ( σ ) U ( σ ) dσ, t ≥ 2...
