4 waves digital oscillator

575

07:08:54

This is one of my favourite circuits now
It's a 4 waves generator only digital! The only analog parts are the resistors and 555 and the capacitor.
All the credits for the sine wave goes to faceblast and our god hurz ;-)
You can regulate the frequency with the 555 by changing resistor's value of the 555.
In this circuit you can see:
Square wave (orange)
Triangle wave (blue)
Saw tooth wave (green)
Sine wave (red)
You can actually build this in real life but i'm going to use arduino for the digital part. 
Happy new year :-)

Can I say that in ec it is quite simulation speed dependent?

Yep not in real life

They are changing phase angle and frequency, when you write the program, make each wave the same length so all 4 waves stay the same frequency.

Interesting concept. If you were to do this with an Arduino, couldn't you eliminate the 555 altogether? I would like to see that code.

Obviously yes @indyTim the circuit in the end will be a potentiometer for frequency and some dacs to turn the digital signal into analog

The code to generate the array is simple but i'm too lazy to write it now :P
