Yes you are right in this, sorry I did not stipulate this, x1= a and x2=ma=mx1

Homework Statement Show that f(x) = x1x2 is a convex function on [a,ma]T where a \geq 0 and m \geq 1. Homework Equations By definition f is convex iff \forall x,y\in \Re \quad \wedge \quad \forall \lambda :\quad 0\le \lambda \le 1\quad \Rightarrow \quad f\left( \lambda x+(1-\lambda...

Not sure you got what I am saying. Even if the max was 640kB , on the photo you can clearly see 27 chips each with 256Kbits of DRAM. This would amount to 6912Kbits in total and thus 864KB. From what I can see that board is equipped with more memory than it can handle, or I might be seeing it...

Hi All, i was looking at the IBM PC XT technical reference and it states that the board can take a maximum of 256K of memory. If you look at the schematic you can then see 36 sockets for memory chips and if you see this picture of it...

Hi, I am trying to build an amplifier with 2 stages, common collector and common emitter. I biased for midpoint operation in them but i have a gain of only 1, don't know where I am going wrong. http://yfrog.com/14amplifierunij Thats the circuit, any help is greatly appreciated

THanks, I just realized what he did, He assumed Ie=IL and Ib=0 since it is very small.

Use the Shockley Diode equation, that should yield an answer.

You could try using the Superposition theorem by first considering one source , then the other, separately, then adding or subtracting the currents as needed.
