Part A: Theory

1.With relevant sketches, define the following with respect to sinusoidal signals: (i) Phase difference, phase lead and phase lag; (ii) Period; (iii) Frequency; (iv) Angular Frequency. 2. For A= 9 + j 7; B = − j 6; C = 6.5 – j 11.1; D = − 85.4 – j 75.8, K = − 56.9 + j 88.8; E= 11∠45º; F = 15∠120º; G = − 46∠140º; and H =− 71∠ (−4π/9). Find: [– ABE / (A+H)], then draw the phasor diagram of the results.
