System function H (s) =1, for a signal cos t, the steady

System function H (s) = ₁ , for a signal cos t, the steady state response is—
s + 1

Given

H(S) =	1	=	1
	S + 1		J + 1

{... cos t = cos t, = 1}
then

h(t) =	1
	2 45°

y(t) = h(t). x(t) =	cos t
	2 45°

= 1/2 cos (t – 45°)

System function H (s) =	₁	, for a signal cos t, the steady state response is—
	s + 1

	₁	cos (1 + 45º)
	2√2
