Left: Wave Generator, Right: Oscilloscope
Mera Arbitrary waveform generator successfully complete ho gya hai. Isme 1Hz to 10MHz ki different wave generate kiya ja skta hai. 11bit good resolution + (may be 2 channel)
Programming aur digital core part complete ho gya.
Ab analog part, amplifier bagara lagana hai....
product coming soon

Aur Yeh smartphone oscilloscope buy krna hai to

Can you give a funny name to this waveform?
I was experimenting with a function generator and some op amp and transistors, then I suddenly came across this....😃

This is an Arbitrary Waveform Generator (AWG) one can generate any kind of waveform he can think of, from this.

A Raspberry pi pico microcontroller is producing 8bit digital signal, then the R-2R resistor ladder is converting it into Analog signal.
This is a good way to use a cheap microcontroller to do something interesting

Some examples of arbitrary Waveforms are given in this post.
This can do also sine triangle, sawtooth, square etc easily. Upto 2.5MHz
