I am tasked to use the DCM in Xilinx's architecture wizard. Can anyone explain what is the function of a DCM and how does it actually work? What are the inputs and outputs of a typical DCM? many thanks!

Oh now i get it. Thanks for the explanation! ;)

so u mean the voltage reading shdnt change? since rms value and dc value are the same.

Happened to come across this qn: Noise from receiver is measured by rms voltmeter with bandwidth 100khz, and voltmeter reads 2mV. what will be the reading for multimeter set to read dc voltage and bandwidth of 10khz? My ans is 10/100 x 2 = 0.2mV. cos smaller bandwidth reduced by a factor...

For measuring the response, my ans is (d). I feel that it shd be ok to input either sinusoids, impulses or even unit step. although the best approach will be to use a sinusoid, bcos using impulses may have a tendency to spoil the loudspeaker. correct me if I'm wrong. As for the qn on...

Thanks for the explanation! Another qn, which of the following is the best technique to measure the response of an audio equalizer? a. input known sinusoid, measure output, change freq and repeat b. input impules, measure output, change freq and repeat c. input unit step, measure output...

If multipath reflection and noise distorts the spectra of the received signal, such that it is different from the orginally transmitted signal, how then does the reciever 'decipher' the originally transmitted signal?

Will the spectra of the transmitted and received signal be different as a result of multipath reflection and noise?

yup. The more impt topics that someone going into such an industry ought to know. Cos there are many courses under the control system but it isn't possible for me to do all of them.

Hi, I am currently choosing my specialisation modules. May i know what are the most important aspects that an electrical engineer should know with regards to "control systems"? Tks :smile:

employment prospects will be my primarily concern after graduation

Hi! I am an electrical engineering undergraduate going into my 3rd yr of my university education. Currently thinking of whether to specialise or not. Any suggestions on why I should or shouldn't? Thanks!

oh i see. Thks!

Does anyone know how to use 4-bit parallel adders to perform 2Cs' subtraction? Thanks.
