You can only use 50Hz,12V rms ac source or/and 5V dc source as and when needed in circuits. Explain your design and discuss your output. Design and simulate circuit using SIMULINK MATLAB only.
1. Design a good positive clamper circuit and simulate for output (voltage and current).
(5 marks)
2. Design a combo positive-negative limiter circuit and simulate for output (voltage and current). Output should be clipped at ±4V.
(5 marks)
3. Design a full wave bridge rectifier circuit and simulate for ouput (voltage and current). Use load resistance 100Ω. Output should be 15V dc. Ripple should be less than 5%.
