Passive Filters - General Questions

An RC high-pass filter consists of a 0.2 F capacitor and a 220  resistor. The output is taken across the resistor. The circuit's critical frequency is

At a certain frequency, the output voltage of a filter is 6 V and the input is 12 V. The voltage ratio in decibels is

V_out = 500 mV, and V_in = 1.3 V. The ratio V_out/ V_in expressed in dB is

A sinusoidal voltage with a peak-to-peak value of 18 V is applied to an RC low-pass filter. If the reactance at the input frequency is zero, the output voltage is

A series resonant band-stop filter consists of a 68  resistor, a 110 mH coil, and a 0.02 F capacitor. The internal resistance, R_W, of the coil is 4 . Input voltage is 200 mV. Output voltage is taken across the coil and capacitor in series. What is the output voltage magnitude at f₀?

An RC high-pass filter consists of an 820  resistor. What is the value of C so that X_c is ten times less than R at an input frequency of 12 kHz?

In a certain low-pass filter, f_c = 3.5 kHz. Its passband is

Referring to Problem 15, if the input voltage is a 6 V sine wave with a dc level of 10 V, what is the output voltage magnitude?
