Calculate the time constant for 1st order circuits with R = 0.5 kΩ, C = 0.2 uF and L =5 mH. Sketch the schematics for four possible 1st order circuits containing either R and C or R and L elements. For each of them draw asymptotic magnitude and phase responses (use a logarithmic scale for frequency). The magnitude response should be presented in dB scale, indicate the characteristic frequencies and -3 dB points.
