What is a sine wave?

This came up when a student asked me. A simple question one might think. Except... how to define one without tautology? That is, without using the word "sine" (or cosine for that matter). Wikipedia does not help, although the moving disc might be of…

Superimposed sine wave

The following circuit modulates the SIG wave with a 1kHz CLK signal and produces the OUT resulting wave. I have read that the superimposed wave has an amplitude of the sum of the original waves. If two waves are ASIN(wt) and BSIN(wt) then the…

Sine to square wave converter

How I can make this sine to square wave converter accept higher frequency? Because when I tested it, it only accepts 10KHZ max. I will need to input a higher level of frequency till 1000KHZ. Would this mean that I need to swap the resistor values…

Sine wave generator frequency

I'm trying to build a sine wave generator following this walkthrough. Specifically, I'm attempting the Clapp circuit as I'm targeting about 113 kHz. Here is the circuit schematic: In the article the author mentions these formulas for calculating…

Generating high frequency resolution sine wave

I want to generate a sine wave with a frequency of exactly 19.999995 kHz. This is possible with a DDS generator implemented inside a FPGA. The DDS signal will be a digital one. So I will use a DAC to make it analog. A DAC with a sampling rate of…

Chart a sine wave, then adapting it to draw a conclusion

I have an unusual request and I am new to this. I was doing an experiment where I was charting electrical values on a Lecher Line (a type of antenna that creates a standing radio wave). I'm using 148.000 MHz. I want to chart the sine wave using…

How can I build a circuit to convert sine waves to square waves at up to 1MHz?

May I ask how do I convert sine waves to square waves at a frequency up to 1MHz? New to digital electronics. Have done some research but not sure which circuit to use/ which is suitable. Appreciate your help. Thanks! Components I have: 74LS14 Hex…

Why are there many oscillators to produce just one sine wave?

There are many oscillators in general but does the same operation of producing sine waves how is that useful?
