You are dancing with the devil, kid. Maybe you have been doing it for years, but one wrong move and you're toast. Get the proper equipment

I think I look kinda like Spock in this picture

I think it means they are physically isolated. That's why you can use a transformer to check line voltages with less risk of dying, there is no connection from the lines to your body, only the stepped down voltage or current.

Well after extensive research (PSpice and a graphing calculator), I've concluded that adding the Miller effect to the parasitic capacitances (treating them as "parallel") gives nearly the same transfer function results as treating them separately. I guess it's just another one of those...

Thanks, looks like exactly what I was looking for! Appreciate it!

Hello all. As a Digital project, I'm trying to construct a digital guitar tuner that will actually tune the guitar for you, all you have to do is put the device on the tuner and pluck a string. My problem is I'm not very mechanically inclined... Does anyone know a tiny hobby motor with a very...

still nothing?? Well, I've consulted with my colleague, and he told me that my interpretation of the miller-effect capacitance was incorrect. He told me that they always goes to ground (can anyone verify this??)...and he also told me to ignore the capacitances Cbe and Cce (ignore? never...

Homework Statement The problem asks to determine the break frequency at the base of Q2 (which is fine I have no problem with that), but the whole assignment never asks for the break frequency at the COLLECTOR of Q1, then later asks to produce a bode plot of the transfer function. See the image...

nevermind...the X's in those equations look like I's... that's retarded

well...i guess I've forgotten a lot of calculus...what does the I in those equations stand for? Integral?

the first point is 0,0, and the 2nd point could be anything, how to i alter the curve to make it pass through my 2nd point?

no, i want to MODIFY a x^3 equation to MAKE it pass through the points i already have set.

I've taken Calculus 1, but it was a few years ago, so bear with me. I understand how to use derivitaves to find critical numbers, relative max's and min's, points of inflections, incresing, decreasing. all that good stuff. my question is, if I have two points I want a x^3 line pass through...
