oh, i double check the formula, if lambda is zero, ro will be infinited, and it will forms open circuit, and yup, there is no body effect. is that corrected??
Re: small signal gain
based on the small signal model i have done, i get the small signal gain as in the following attached file, please someone help me look at it , thanks a lot.
the question is required to find the small signal gain, in the attached file, shown the small signal model that i have done, please someone help me to look at it, tell me it is right or wrong, and if possible , tell me the small signal gain. thank you very much.
if i use raised cosine pulse shaping, so how can i do it, because i have no time to read the digital communication textbook now, so with the modulation is 16QAM, and total bandwidth is 1200MHz, which is from 950MHz to 2150MHz. the symbol rate is 45MS/s, in general, it is 4 bit per symbol,how to...
if C is a constant, how can i make a block have function C^(x), in order to achieve the control input,which will be constant increase or decrease in dB?
if not a precise calculation, how can i calculate it, because i have to show something as soon as possible, and use the channel width for other more complex calculations
i have problem to calculate the channel width now. i know the modulation is 16QAM, and total bandwidth is 1200MHz, which is from 950MHz to 2150MHz. the symbol rate is 45MS/s, in general, it is 4 bit per symbol, i have no clue how to calculate the channel width base on these information, my...
can anyone tell me is there a block in simulink have a control input can change the gain of the block, just like a normal gain block and have additional input can change the gain somehow?? please help me, thank you very much to everyone...
thanks, i am trying to accomplish a system level design to achieve specification for a DVB-S2 standart satellite tunner( i can say a 16QAM receiver). yup , my receiver will work with a AGC, somebody gonna design the AGC, but i have better to design myself also. and what will you use to start...
