1. For the lowpass RC filter, calculate the phase and magnitude ofthe transfer function at frequencies of 20, 50, 100, 200, 500,1000, and 1500 Hz. Tabulate the result and then sketch themagnitude and the phase of the response as function of thefrequency (use log scale for frequency). Use R=50 kΩ, C=0.02μF
2. Determine the half power frequency fc defined as the frequencyat which the magnitude of the transfer function is at 1/√2 ofits maximum value. Assuming C is fixed at 0.02 μF, calculatethe half power frequencies corresponding to R=20 kΩ, 50kΩ, and 100 kΩ.
