A square wave oscillator

[Monsu]

I have a question as to how to design an oscillator that will produce a wave such as the one I have attached. It is a square wave, but with changing times, first half wave with time 20ms, and second half wave with 5ms. Also, how could i make this oscillator then produce a triangular wave.

Two oscillators with different frequencies and offsets pumped into an OR gate should do it.

As for producing the triangular wave, someone else will have to answer the question

[chroot]

To get a triangle wave from a square wave, use an op-amp wired up as an integrator.

How did you post that image?
I have schematics of many waveform generators.
