synchronization

[entsecy]

Hii I have a sine wave of freq 50 Hz stepped down from a transformer and a triangular wave generated from IC8038 with freq 3KHz now i have to synchronize these two waves so that my pulse width modulation wave obtained from these two waves on inputing to a comparator has a quarter wave symmetry.

Please HELP!!!!!

Homework?

We don't do homework!

What have you come up with so far. You can’t synchronise them but you can superimpose them.

Exactly what i was thinking Tony :joker:

I'm surprised that they are still teaching with the IC 8083 as it's nearly obsolete. The analog Function generator has been taken over due to the rise of direct digital synthesis (DDS). This one is popular in several designs seen on the web: http://www.analog.com/static/importe...ets/AD9835.pdf. Have a word with your lecturer, he's waiting your time, it's a bit like teaching oc81's

You need to detect the zero volts cross over of the 50HZ and generate a pulse to synchronise the 3Khz oscillator.

You then need to generate the 3Khz using a VCO, or possibly generate the 3KHz using a precision Xtal oscillator and then divide down to 3Khz.

That's why you can part water Moses clever man ha ha

I've turned to the beer thinking about it lol

You understand that's not my real name, of course!!!

I only use that name because I believe in him as one of the greatest Prophets of GOD.

I'am not clever and I can't part waters, yet!

I am only here to learn from some, and pass-on what I have learned to others.
