3) Demonstrate clipping of negative waves with an inverted diode in the output. A circuit which removes the peak of a waveform is known as a clipper. Show a negative clipper. Produce a schematic diagram with LTspice schematic capture program. During the positive half cycle of the 5 V peak input, the diode is reversed biased. The diode does not conduct. It is as if the diode were not there. Show the positive half cycle is unchanged at the output V(2). Show the output positive peaks overlays the input sinewave V(1). Use in the LTSPICE display module, the command "plot v(1)+1)" accomplishes this. Voltage values: Resistor valuse: 1 ΚΩ DC offset: 0 V Amplitude: 5 V Freq: 1 KHz
