Are DC square waves made up of AC sine waves?
Mar 11, 2025 · The Wikipedia page on square waves shows that they are made up of many sine waves, using Fourier analysis. For an experiment, I made a simple square wave using a micro …
Why do square waves have this spectrum response?
Below shows my makeshift spectrum analyser, where a 2V, 66Hz square wave on the input. Why do square have have this response (where every harmonic has some amplitude attached to it)?
How can I convert a high frequency sine signal to a square wave?
Oct 18, 2023 · 1 I'm trying to convert a high frequency sine wave signal (approximately 130 MHz) with lets say 3 Vpp into a square wave signal (also 130 MHz) with 0V and 5Vp. The square …
Frequency of square wave - Electrical Engineering Stack Exchange
A square wave behaves the exact same way as a sine wave, in that as its fundamental frequency increases, you will see more cycles in a given amount of time. Square waves theoretically …
FFT of a square wave - Electrical Engineering Stack Exchange
Dec 26, 2019 · Your signal is a square wave with its base at 0V and its peak at 2.7V or so. So it has an average voltage of 1.35V. In the frequency domain, the overall average of a signal is its …

May 6, 2022 · What I understood from the internet is that DC coupling lets the signal through to the scope directly whilst AC coupling uses a high-pass filter - a capacitor, which removes …
What can reduce overshoot and ringing on a simple square wave …
I've built a simple RC and Schmitt-trigger-based square wave pulse generator. On the breadboard, it has some obvious unwanted qualities due to jumper length, the breadboard …
How to distort a square waveform to get even harmonics?
Jun 25, 2024 · This is the output scope of an analog square wave signal (0-9 V) going through a NPN transistor VCA modulated by a variable voltage to alter the output amplitude. the …
What would cause a square wave to become rounded?
Dec 24, 2019 · Every "square wave" is actually closer to a trapezoid in shape with sloped edges. The slope of these edges can be used to determine how high up the frequency content of your …
