Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum negative amplitudes of a waveform, as shown below. If there is no direct current ( DC ) component in an alternating current ( AC ) wave, then the pk-pk amplitude is twice the peak amplitude. So peak-to-peak voltage is exactly double the value of the peak voltage of a waveform. Examples of Peak-to-Peak Voltage. You will encounter peak-to-peak voltage in many environments. However, never assume a voltage is peak-to-peak unless directly specified as that. For example, the voltage should say at the end, VPP. For example, 60VPP.

You have noticed how LTspice sets the amplitude of a sine wave as the peak voltage. That is why you specify a 170 Vpeak sinewave rather than 120 Vrms.

23/08/2006В В· value, which is 0.707 of the peak voltage for a sinusoid. This is the voltage definition most commonly encountered in the electrical power field, as it is the "effective" voltage (i.e., the one you would use in power calculations for resistive loads - for instance, a 100 V (RMS) AC supply results in the same The Peak-to-peak Voltage calculator calculates the peak-to-peak Voltage, VP-P, value from either the peak voltage, the RMS voltage, or the average voltage. It calculates the peak-to-peak Voltage based on the above formulas for each respectively. To compute VP-P from the peak voltage, the peak voltage вЂ¦

24/10/2003В В· Does anyone here knows how to measure the peak of a wave in LTSpice? Thanks. Predicting the efficiency of an application is vital to evaluating design trade-offs of a switching mode power supply. Two useful tools, the .step and .meas commands, can be used to calculate and plot efficiency over a range of load currents.To evaluate efficiency, clearly label your input and output voltage net as IN and OUT, respectively.

The typical resistor is Вј W and if asked to dissipate 8.1 W will die in a puff of smoke. This calculator shows the peak-to-peak voltage (VP-P) value from the peak voltage, RMS voltage, or average voltage. Peak to Peak Voltage Calculator (VP-P) - вЂ¦

The strength or volume of sound. By increasing the amplitude you enlargens the energy because the difference between peak negative and peak positive voltage in the waveform gets bigger. 02/04/2016В В· This video shows that how can we measure pk-pk and RMS voltage using multisim.

06/06/2014В В· Hello folks, I'm trying to perform some stability analysis in LTspice of an op amp. I am trying to meas the exact phase margin using a .meas statement.meas ac res4 FIND ph(V(out)/V(in,out)) when mag(V(out)/V(in,out))=1 This tells LTspice to create a variable called 'res4' whose result is the phase of the open loop gain when the magnitude of the open loop gain is 0dB.

27/07/2014В В· I've made quite a lot of use of LTspice and haven't come across any automatic way to find the maximum of a plot. What I've been doing instead is using the ability to zoom in on sections of the plot to magnify the area of interest, making finding the maximum (or minimum) easier. Still need to вЂ¦ The strength or volume of sound.

.MEASURE -- Evaluate User-Defined Electrical Quantities . There are two basic different types of .MEASURE statements. Those that refer to a point along the abscissa (the independent variable plotted along the horizontal axis, i.e., the time axis of a .tran analysis) and .MEASURE statements that refer to a range over the abscissa. A "Quick Window Integral" Method in LTspice WaveForm Viewer. There is a way to ask the LTspice WaveForm Viewer to provide a quick definite integral calculation of certain types of signals (instantaneous power being one of them). This can actually be quite useful if the definite integral is desired to be performed over a time period bounded by
