Question

Need help with part 6 please. 

If you can at least do p6 a/b I would appreciate it and I can see how to do the remaining parts by following the work. 

 

Thank you

1. The input voltage for the series RLC circuit shown in Figure 1 is Vs (t) = cos(@t) volts (2-volt
peak-to-peak). The angular frequency is = 2nf rad/sec, and fis the frequency in Hz. The
output is the voltage across the external resistor, V (t). As we have discussed in previous
experiments, the signal generator has an internal resistance of Rin= 500. For this problem,
just use the element names R, L, C, Rin (and not the numerical values).
(a) Find the input-output frequency response, H₁(jo)=
generator
(b) Find the magnitude (gain), H₂(jo), and the phase shift, ZH, (jo).
(c) What is the DC gain, H,(0)?
(d) What is the gain at high frequencies?

2. Recall the actual p-p voltage supplied by the signal generator is the open-circuit p-p voltage
as shown in Figure 1. (For the laboratory discovery, make sure the open-circuit p-p voltage is
2 volts before connecting the circuit elements (R, L, C) to build the circuit shown in Figure
1.) If we use an oscilloscope to measure the voltage across the generator, we are actually
measuring the voltage, V₁(t), across the terminals AB. If V (t) = cos(ot) volts (open-circuit
generator voltage), what is the phasor, V₁, of the measured voltage across the generator?
3. By inspection of the circuit, explain why the measured peak voltage across the generator
(peak of V₁(t)) is close to the peak voltage of Vs (t) (which is 1V) at low (DC) and high
frequencies.
4. Use the result in Q.1 to find the resonant frequency of the circuit when C= 4.7nF. L=1mH,
and R= 51 ohm.
5. For Vs (t) = cos(@t) volts, find V and VR when f= 5 kHz, 70 kHz, 100 kHz and 1MHz
when C= 4.7nF. L=1mH, and R= 51 ohm.
6. Also find V₁ and 2 V, when f= 5 kHz, 70 kHz, 100 kHz and 1MHz
