Question

3) An antenna has input impedance equal to 400 $\Omega$ is connected to the television receiver. The bandwidth of the receiver is 6 MHz a) What is the value of the resistor that matches the receiver input impedance and should to be connected across its antenna b) If 600$\Omega$ resistor is connected across the receiver input, what is the equivalent noise voltage applied to the receiver input. [assume room temperature =293K] c) If 300$\Omega$ resistor is connected across the receiver input with input power signal equal to 2mW, what is the signal to noise ratio at the input of the receiver. [assume room temperature =293K] d) If 500$\Omega$ resistor is connected across the receiver input with external noise equal to zero, what is the value of the minimum input voltage signal at the receiver input? [assume room temperature =293K]
