Problem: In electronics device laboratory, you need to use the function generator to use different types of signals e.g., sinusoidal wave, square waves, sawtooth waves and so on. Imagine you are planning to make an approximate square wave generator from a sinusoidal wave having peak voltage of [three digits before last digit of your ID] mV to use the produced square wave to study the clamper circuit. You can consider any frequency. You need to avoid using any dc power supply to save the energy. Also consider the amplitude of the produced square wave must be greater than the PIV of the diode. 1. Identify which circuit is necessary for making the generator. Illustrate input-output signals with appropriate labeling. 2. Lift the produced square wave above the x axis by the amount of [your last digit of your ID] V explaining appropriate steps. + Sinusoidal PIV
