  1. What is a sine wave? - Electrical Engineering Stack Exchange

    May 23, 2018 · And the x and y co-ordinates of a point on a circle are deeply related to the definitions of cos and sin. If you know what a sine function looks like when graphed, you already know what a sine …

  2. Peak to Peak vs. Amplitude - Electrical Engineering Stack Exchange

    Jun 27, 2017 · For a sine wave, Amplitude is the fluctuation or displacement of the wave from its mean value. Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum …

  3. What exactly are harmonics and how do they "appear"?

    May 21, 2012 · I get the impression that you're using "harmonics" colloquially - higher frequency disturbance. Harmonics (frequencies) are tied into the definition of the Fourier series decomposition - …

  4. terminology - Confusion regarding term "offset"? - Electrical ...

    1V peak-to-peak AC sine wave signal, with an average voltage of +2V is said to have a +2V offset. A function generator can add an offset (DC bias) to generate such a signal. For example, to make a 5V …

  5. RMS of sine wave curve defined between two points

    Jun 18, 2024 · P.S. in the general case mentioned in your title "sine wave defined between two points" you would, in general, find the trig functions don't disappear if you don't hit the integral multiples of …

  6. inverter - Why the triangle reference wave is used in PWM for sine ...

    Mar 20, 2020 · Thank you for your response—it addresses most of my questions! However, I'm still not entirely "satisfied" with the explanation. My main question is understanding the mathematical proof or …

  7. Why V rms instead of V average? - Electrical Engineering Stack Exchange

    By definition we are looking for equivalent AC and DC power. Power is a function of the square of the voltage (Power=V²/R). Finding the square of a DC voltage is easy. How do we find the square of a …

  8. rf - What are the waveforms of radio frequencies? - Electrical ...

    Dec 15, 2020 · First, what do you mean with Radio Frequencies? an unmodulated signal? a modulated signal? if so, what kind of modulation do you mean AM, FM, PM? Do you mean a waveform in air or …

  9. Slew Rate Explanation - Electrical Engineering Stack Exchange

    Nov 12, 2020 · This means that for example when a large sine wave causes slew rate limitation or distortion, the sine starts to resemble a triangle due to the constant current charging the cap. …

  10. Average value and RMS value - Electrical Engineering Stack Exchange

    Nov 23, 2021 · The average is obviously zero for a sine wave with no offset since the area above and below zero is the same. For a triangle wave, the RMS value is the same as for a sawtooth of the …
