Filters Q. No. 1: Find the transfer function V0 Vs of the circuit in Figure 1. Determine what type of filter is it. Q. No. 2: Show that a series LR circuit is a Lowpass filter if the output is taken across the resistor. Calculate the cutoff frequency fc if L=2mH and R = 10KΩ . Q. No. 3: Find the value of the resistor in an RL Lowpass filter that uses a 40mH coil and has a cuttoff frequency of 5KHz. Q. No. 4: Determine what type of filter is in Figure 2. Calculate the cuttoff frequency fc. Q. No. 5: Determine the range of frequencies that will be passed by a series RLC Bandpass filter with R = 10Ω, L = 25mH, and C = 0.4µF.
