### Transfer functions and steady state

1. The impulse response for a circuit is h(t)=e^(-t), t>=0. What is the response function of the circuit in the s-domain if the input is f(t)=cos(2t)? 2. The transfer function for a circuit is H(s)=1/((s+2)(s+5)). What are the poles? Is this an impulse response stable circuit? 3. The transfer function for a circuit is H(
