sinusoidal

I made this oscillator and the output voltage is 1V, and I need another amplifier to go to 5V and some mv ideally to 10mV, but that is harder. I made this but it doesn't work very well and I don't understand why. I can't work with OpAmps, with only transistors. I put a common emitter with a...

I tried to estimate angular acceleration of a shaft with angular velocity points collected from an incremental encoder but, when I differenciate numerically, errors of estimation became very high due to the delay in capturing flanks (detecting slits). What alternatives do you suggest for my...

The was an equation given like that: v(t) = 5cos(1256t-pi/4) Then I wanted to draw this graph below: Do I need to scroll the chart left or right? (In the cosine graph, I shifted it to the left side) Also I want to ask that, I have been always encountered with sine function graph drawings...

Here is the i (graph a) and i^2 graph (graph b) for the RMS calculation: My question is while calculating RMS value, should I decide to determine the period by looking a) or b) graph? Because, while I'm looking for the a. graph (shown above), I guessed the period is 2pi However, if I would...
