A

5- Solve and convert the following to phase domain then, time domain: (a) (5+j6) + (10+j6) (9+8)-(3-j1) (b) (60160) (3+j30) 20 -11

2. Calculate the phase shift for an RC lag circuit for each of the following frequencies, and then plot the curve of phase shift versus frequency. Assume fc= 100 Hz. (15)• f = 1 Hz • f = 10 Hz• f = 100 Hz• f = 1000 Hz • f = 10,000 Hz
