Enter the answer along to 3 significant figures. include screen dumps of each circuit schematic, natlist and simulation results
Question 3 (50 marks) With reference to the circuit in Fig. 3: 50% (a) sketch the current IRL flowing from the diode to ground via resistor RL in steady state, i.e. after any transient has settled; 50% (b) calculate the maximum value and period of Irl(t) in steady state. = Vs = A sin (wt), A = (1000 + ε) mV, f = 4 kHz. Rs = 10 , RL = (5,000+ n) n. Hint: To simplify your calculations, you may assume the diode is ideal. Rs * Vout Vs RL Figure 3 Sketch of Irl(t) Include an image here or refer to your scanned workings Maximum value of Irl(t) Period of IRL(t)
