Arbitrary Signal

Hi..
Do you have any opinion that can I produce an arbitrary signal using PWM?
Or is there any way to produce an arbitrary signal with pic?
Thanks for your anwers..

Q: Can you produce an arbitrary signal with PWM?
A: No

Q: Can you produce an arbitrary signal with a PIC?
A: No

If you tell us what kind of signal you are interested in, then maybe we can help you.

arbitrary ...... did you mean random?

I think by arbitrary the OP means a recorded complex waveform as apposed to a sine, square or other repetitive waveform. He can do this with a PIC, LPF and PWM as long as the highest frequency is much lower than the PWM frequency and the PIC has enough memory to store the sample.
