voltage @ angle, single phase sinewave

\[V=V_{\small PK\sim}*sin(\Theta)\]

angle @ voltage, single phase sinewave:

\[\Theta=arcsin(\frac{V}{V_{PK\sim}})\]

one or all forms (might wanna make sure these are right... )

\[C=I(\frac{\partial T}{\partial V})\]

\[C=(\frac{V_{PK\sim}}{\omega \cdot V_{ripple}})R_{\small Load}\]

\[C=(\frac{V_{PK\sim}}{2 \cdot \pi \cdot f \cdot V_{ripple}})R_{\small Load}\]

Possibly add for sinewaves

\[V__{\small PK\sim}=V_{\small RMS}\sqrt{2}\]

Under Digital reference, a quick lookup table of 54/74xx, 40/45xx logic, at least number -> description, preferably pinout, though those would be a nightmare, I could help if you have a standard format for IC layout. ++SuperNifty Points for adding gates inside pinout for the simpler IC's, as is done in Newnes Electronics Engineer's Pocketbook.

Finally, In Digital Reference or uC, I'll post some code for PWM routines in C.

On that note, can the C / Assembly code colorizer module for vB be added?
