Answer question 2

Suppose the FET chosen for the circuit given also had λ = 0.015 V−1. What are the values of ro and the new voltage gain? (Use the Q-point values from the example.) Does neglecting the output resistance seem a reasonable thing to do?

Consider a system with a closed loop transfer function defined by 16 H(s) = %3D 3s2 + 8s + 48 Let the input signal is r(t) = u(t) %3! Then, the peak time is 0.277 seconds O 0.785 seconds 0.833 seconds 0.261 seconds O 0.675 seconds

Can anyone help me with this circuits question. I don’t need the design of the BW LPF just the hand calculations. Thank you

An electric circuit, whether it's a simple lightbulb or a complex amplifier, has two input terminals that are connected to the two output terminals of the voltage source. The impedance between the two input terminals (often a function of frequency) is the circuit's input impedance. Most circuits are designed to have a large input impedance. To see why, suppose you need to amplify the output of a high-pass filter that is constructed with a 1.6 k resistor and a 15 uF capacitor. The amplifier you've chosen has a purely resistive input impedance. Part A For a 60 Hz signal, what is the ratio VR load/VR noload of the filter's peak voltage output with (load) and without (no load) the amplifier connected if the amplifier's input impedance is 1.5 ks2? ΑΣΦ -> VR load/VR noload = Submit Request Answer Part B For a 60 Hz signal, what is the ratio VR load/VR noload of the filter's peak voltage output with (load) and without (no load) the amplifier connected if the amplifier's input impedance is 150…
