May 7, 2018 · Power of a sine wave is not dependent on the period (or frequency for that matter). It is only computed from the root mean square (RMS) value of your sine wave and the phase difference between current and voltage. RMS value is given by dividing the peak value of a signal (voltage for example) by the square root of 2.

Apr 6, 2015 · I need to transform a bipolar sine wave (varies from -5 V to 5 V, 1 kHz) to a square wave for further digital processing (0 to 3.3 V), as in this image: The important thing is that this sine wave can't be distorted, so there can't be any limiting diodes at the input. I have got only 3.3 V and 5 V voltage supplies.

Aug 24, 2021 · The idea, if I understand correctly, is that the sine wave filter smoothes the output, eliminating the spikes at the edges of the PWM pulses. I'm installing a variable frequency drive in a setting where I have a very well insulated short length of cable. The specifications in the VFD manual do not suggest I am close to needing a sine wave filter.

May 23, 2018 · A sine wave is a repetitive change or motion which, when plotted as a graph, has the same shape as the sine function. A quote more directed to electronics: The electrical power in your house is AC or Alternating Current.

Mar 20, 2012 · The average value would be equal to zero as the positive and negative halves will cancel each other out if the average value is calculated over the full cycle in a pure sine wave. In the image below, the average or mean value of an AC waveform is calculated or measured over a …

Jan 24, 2023 · I generated sine wave from 0 to 3.3V and its has a 1.65V offset value. I need a sine wave from -1.65V to 1.65V using MCU. Use a coupling capacitor (a.k.a. DC blocking capacitor): simulate this circuit – Schematic created using CircuitLab. RL represents the input impedance of the load. For technical explanation purposes I put 10k but can be ...

Oct 22, 2021 · If you need a user-defined source (i.e. not a normal sine source) in the future, you can also insert a VPWL_FILE from the library and have it point to the text file. You can write a program that creates a text file and writes a few values …

Jul 3, 2019 · Cosine is basically sine with a phase. phase of 180° will completely invert your signal. DC Offset adds a DC level to your sine wave signal e.g. 1V DC Offset means your sine wave will "oscillate" around 1V rather than 0V. Frequency is the number of cycles the sine wave will complete in a second. Tdelay adds delay before starting the source.

Feb 17, 2018 · Just model the circuit with with highest and lowest loads and see what happens to the shape of the sine wave and its amplitude. I'd consider starting with L = 10 mH and C = 3.3 uF (876 Hz) with a little series resistance with the inductor to avoid Q factor rising too high on low output currents.

Mar 27, 2017 · A cosine and sine wave are essentially phase-shifted versions of one another. For instance, \begin{equation*} cos(x+\phi) = sin(x+\phi-90) = sin(x+\theta) \end{equation*} where \begin{equation*} \theta = \phi-90 \end{equation*} Hence, a cosine and sine wave are essentially the same, and what differentiates their use is the value of the initial ...
