C1 Hc Vin R1 R Vout Figure 1 Simple RC Circuit #1 1) (4 pts) Determine (analytically) if this is a high pass, low pass, band pass or band stop filter. Approximation methods are acceptable. Hint: What happens as w → 0, w → 00? 2) (4 pts) Determine the cutoff (-3 dB) frequency wų as a function of R1 and C1. Submit it as answer 2. 3a) (2 pts) Assuming that you are limited to 1.5K, 15K, and 150K resistors, and capacitors of 300 nF, 15 nF, and 560 pF, select the proper components for a (-3 dB) frequency of approximately 4.44 krad/sec. Submit the value of C1 as answer 3a. 3b) (2 pts) Submit the value of R1 as answer 3b. 4) (4 pts) Make the usual substitution s = jw and write the transfer function Vout(s) H(s) = for this circuit. Submit it as answer 4. Vin(s) (4 pts) Substitute the value of w, as appropriate and provide the numerical value of the magnitude complex transfer function |H()ls=jwę. Submit the value as answer 5. 5) 6) (10 pts) Using your selected component values, confirm your analysis by simulation using LTSPICE. Print the frequency response to PDF, combine with the other plots as Lab Final Details.
