during the negative part of the input voltage. Voltage drop at Diode 1 is limited at -0.7v. whenthe input voltage goes above -0.7, the diode is no longer forward-biased and a voltage appears across RL proportional to the input voltage. Clampers circuit is different from clippers because clamping circuit uses a diode connection and a capacitor. The diode conducts and acts like a short circuit during the negative half cycle of the input signal. The output voltage VO = 0 volts. The capacitor is charged to the peak value input voltage Vm andit behaves like a battery. During the positive half of the positive half of the input signal, the diode does not conduct and acts an open circuit. Hence the output voltage is Vo =Vm+Vm which results a positive clamped voltage. Besides, through this experiment we also learn howto connect the clipping and clamping circuit on the breadboard while receiving the correct results from the oscilloscope. We also understand the waveform change of diode clipping circuit and clamping circuit when the two-different bias is applied and also, we learn how to calculate oscilloscope results by using Vp-p. The peak-to-peak value of a sine wave is the voltage or current from the positive peak to the negative peak. Where: Vpp=2Vp and Ipp=2Ip. In this experiment, we learn how to use oscilloscope and to get the wave based on question which given. Limiter are used to add a DC voltage to an AC voltage.
