# sinusoidal and square signal

usually as some sort of Electronic Reference

So do you think is a powerful stuff if we can generate those kind of waves ??

Powerful like influencing certain behaviors? Sure.

I don't understand, could you details more please ??

Well, Nicola Tesla used sine waves for inventions that enable civilization as we know it. :) But you're a little late for that.

BulldogLowell: have you tried to google "(Arduino) waveform generator"?

by the way: do you know a very simple method to generate a sinus wave without complex math?

Try that:

``````float y;
float x;
float z;

void setup()
{
y=100;
x=0;
z=0,01;
}

void loop()
{
x=x+(y*z);
y=y-(x*z);
}
``````

That's it! x is a sinus, y is a cosinus.

Amazing isn't it?

Original Syntax Errors corrected.

Except for the syntax errors.

A square wave contains an infinite number of of odd harmonics. A sin wave is the fundamental building block of all waveform.

So for an amplifier its square wave response tells you about the bandwidth of the amplifier where as a sin wave tells you precisely the response at that specific frequency.

Grumpy_Mike thanks, could you give me an indistrual application when we use those waves, thanks in witch domain we use those waves thanks

***Sine waves*** Application: AC electric power Domain: Global industrial and domestic power distribution network

Thanks

A single square wave is used to measure the impulse response of a system. For example you would use a clap to measure the reverberation in a room. A single explosion is used as the excitation for geological echo returns. Or square waves are used in eddy current flaw detectors for checking tubes for internal fractures.

Sin waves are used for finding the resonate frequency of structures like buildings and bridges. Radio communication involves the generation of sin waves.

I hope I get some good marks for this homework of yours.

thanks

Did you get stuck with it?

RIN67630: Did you get stuck with it?

There are a lot of beginners on this forum. It sets a bad example.

RIN67630: Did you get stuck with it?

Well no but it was totally irrelevant to the question asked. The OP was not looking to generate a wave, he wanted to know the uses of them for his homework.

SCNR.

RIN67630: And newly added: gravitation waves.

SCNR.

You just don't get it do you.

The OP is asking about square waves and sin waves, these are wave shapes. Gravity waves are not a wave shape.

Also the OP was asking about applications. Do you know of any industrial applications for gravity waves? Read before you post.

How about the research industry? ;)
