what I've done is put 15V Vcc and the max out on the 741 is about 13V. so that 13V output i'll just shrink the amplitude to get my desired value.

i'm limited to resistors, opamps and capacitors. My full circuit it a waveform generator. the bi-state multivibrator output is acting as a square wave generator. and i want a 8vp-p value. but if i put 4V and -4V for Vcc and -Vcc it'll def be saturated and inaccurate.

looking for a way to calculate it so i can apply it to different Vcc voltages

well open loop gain is so big that it'll, ideally saturate at Vcc and -Vcc. but practically it'll saturate at a lower value ( 10V saturate to 9.11V). i want to increase Vcc and -Vcc such that i can compensate for this decrease in output voltage. so in order to saturate at say 10V I need to...

Hi, I'm trying to understand how to correct when you put Vcc as 10V your max output is like 9.18V. Is there a factor on the data sheet or what? I'm trying to build a bi-state multivibrator to generate a 10V peak value but it's being saturated. thanks.

hey, I've hit a bump in the road here. I'm trying to build code for a hash table out of my textbooks pseudo code, and I'm not quite sure how I'd represent a string of characters such as "thisISastring", as an integer for my key variable. I'm using division method if that helps at all. I know the...

yeah I kinda knew the n wasn't supposed to be there, but i put it in just in case i was wrong. your solution makes total sense, thank you very much!

Hi, I've been looking through my algorithms book/notes and I've come across this summation I'm not quite sure how they got to. \sum^{lgn - 1}_{i = 0}\frac{n}{lgn - i} = n\sum^{lgn}_{i = 1}\frac{n}{i} where lgn = log_{2}n, it's just to make it simpler any clue? cheers,

hey, I've been looking at ways to create a LED chaser using a 555 timer chip and 2 x 4017 decade counter chips(more than 10 LEDs). mind you I've only been working with these chips for an hour. so here's the dilemma, I'm not quite sure if I'm right on connecting the 2 chips. what i did was...

omg...too stressed out about finals...i think i got it =_= please correct me if I'm wrong (again)... a(t) = -\omega^{2}r(t)

This problem has been discussed before, but one of the parts were not discussed. Homework Statement Your calculation is actually a derivation of the centripetal acceleration. To see this, express the acceleration of the particle in terms of its position r(t). r(t) = Rcos(\omega...

it was late...i changed the units, i was just used to m/s^{2} from previous physics courses...
