Hi,

please I need your help for his question.

please take a look to the attachment.

3- The output of a linear system is yf=10e40054t when the input is xf=e4u{t). Find the transfer function of the system and its impulse response. 4- Model the differential equation :1: 18 g + W = 32 using operational amplier ("op amp") and other circuit components (resistor, capacitor, etc. }
