Using the component values given in practical Problem 1, plot the maximum gain in decibels versus ß when ω is inifinite. Let ß vary from 0 to 1 in increments of 0.1.

Problem 1

In the circuit of Fig. 1 the component values are R1 = R2 = 20 kΩ, R3 = 5.9 kΩ, R4 = 500 kΩ, and C2 = 2.7nF.

a) Calculate the maximum boost in decibels.

---

b) Calculate the maximum cut in decibels.

---

c) Is R4 significantly greater than Ro?

---

d) When ß = 1, what is the boost in decibels when ω = 1/R3C2?

---

e) When ß = 0, what is the cut in decibels when ω = 1/R3C2?

---

f) Based on the results obtained in (d) and (e), what is the significance of the frequency 1/R3C2 when
