Calculate the cutoff frequency of the circuit. R₁ = 2.02 KQ, R2 = 2.02 kQ, C₁ = 0.05 uF, C₂ = 0.05 uF RG = = 15 ΚΩ, RF = 40 ΚΩ Note: Express your answer in Hz and in 2 decimal places. No need to write the unit. V₁ C₁ HA R₁ RG C₂ R₂ RF Op-amp V₂

Given the circuit below, find the output voltage vout measured across the resistor. You are told that vs = 20 cos (10t + 40°), and you may assume that C= 38 µF and R = 1,969 0. R Vout Vs Once you have found the output voltage, enter the magnitude of the output voltage (in volts) below, to 3 significant figures.

The circuit in the figure is supplied with a sinusoidal alternating voltage. a) Calculate the source voltage U. c) Calculate the active power d) Determine the impedance of the circuit
