    why discrete sine transform is not used in Image compression

    Re: why discrete sine transform is not used in Image compres if you use dst instead of dct, then your main focus ie the spot where the majority of the energy condenses is at the center I think instead of one corner as in the dct

    Difference between ECL and CMOS Technology

    difference between ecl and cmos speed man the main difference is speed cmos is a turtle if you compare it with ecl

    Why need to used a very small channel lenght and channel width when designing MOSFET?

    Re: MOSFET not always just for digital cell design you want to have the fastest ones, but for analog using the shortest channel lenght could be a trouble, just follow the eight commands for layout ....

    AM, FM, PM Modulation Question

    am fm pm wiki if you have a signal a high frequency one, the you can send information of a slow frequency signal on within it, if you vary the amplitude of the hf signal you have am, if you slightly modify the frequneyc i se less than 5% you have fm, and if you change its phase with respecto to...

    why we mostly use capacitance at the output of circuit?

    To decouple signals, this is to block off, the dc component from one stage to other stage, it just dependes where you put connect the capacitor shunts or series?

    conductor and semiconductor

    Let us imagine that we have a piece of a material with a controllable resistance, i.e., it can be near zero as a a conductor or a metal wire, or can it be near infinity, as the isolators, a semiconductor is that, a material which resistance can be changed either to grow or to decrease depending...
