I have a question as to how to design an oscillator that will produce a wave such as the one I have attached. It is a square wave, but with changing times, first half wave with time 20ms, and second half wave with 5ms. Also, how could i make this oscillator then produce a triangular wave.

HI, When doing some calculations for a JFET (n-channel), I guess u all know this equation: Id = Idss( 1 - (Ugs/Up))^2 my question is, am i supposed to take the absolute values (modulus) of Ugs and Up? Id = drain current Idss = saturated drain-source current Ugs = gate-source voltage...

hi, pleaaaaaaaaaase! i need help urgently! I am completely stuck! I have no idea what to do on this question, it reads thus: Given the following datatypes for boolean formulae and the truth values datatype boolexp = bez | beo (*0 and 1*) | bep of...

hi, i want to ask, what is the impedance across a resisitor? isn't it just the value of the resistor? say i have a resistor of 50ohms, then its impedance is 50ohms, right?? thanks!

You are given a low pass filter of 50nF and a resistor of 100 KOhm. a) Draw the circuit diagram; b) Calculate the 3dB frequency; c) Calculate the impedance of the series circuit of R and C and draw it in the complex plane at about 2 decades around the 3dB point and at the 3dB point. d)...

hey, i was just confused here, which is the right formula for finding the self inductance of a solenoid, given the number of turns, the cross-sectional area, the length, and the current. is it L = Uo x Ur x N^2 x A / L (Uo = mu o, Ur = mu r)?? pls if it is wrong, let me know the right...

hi,here is my question. water comes through a shower, the speed in the pipe is Xm/s how does this change when the water comes through the little holes in the shower head. I have the number of holes and their diameter and also the diameter of the pipe. how would i find the speed of the...

hey that sure sounds interesting, so how sensitive would my ear phones have to be if i wanted to that without a tape recorder? thanks! Monsu.

could someone pls post a site for a tutorial (preferably interactive) for sml programming. I know it itsn't a language in very common use, but I have to learn it in my University. thanks for any help!

hi, could anyone guide as to how to go about solving this question? [B]A cicular patch of grass or radius 20m is surrounded by a walkway and a light is placed atop a lamppost at the circle's center. At what height shoud the light be placed to illuminate the walkway most strongly? The intensity...

it was a common emitter configuration. here 's a diagram.

all I did was measure the storage time, delay time, rise time and fall time. I didn't do anything with the current. pls help! totally confused! Monsurat.

hi, could anyone pls tell me why the storage time of a transistor changes as u change the position of one resistor? During an experiment, when the resistor connected to the base voltage was reconnected to the ground i noticed that the storage time increased. pls someone explain to me why...

the storage time is the time needed for minority carrier concentration in the vincinity of pn junction to be reduced to zero
