I' m currently trying to make synthesis (with synopsys) a block with 3sublocks which work in diferent voltage. Of cource between these blocks have to be added level shifters. Is there anybody to know how to define the level shifters in the script?
Thank you in advance......
Hi
I want to transmmit dc levels using wireless RF modules. More accurately, I need a wireless link in order to transmmit 16 diferent dc levels of the same duration.
Is there anybody to suggest me some such modules? Thanks!
I atempt to construct a signal with 17 different voltages. What someone can observe at the signal are glitces at the begining of each analog voltage and more specifically more stressfull when the amplitude of previous voltage has big difference from the amplitude of current voltage. Is there...
Re: pll calibration
The frequency of the clock, in other words the symbol rate (rate at which signal goes from one frequency to another frequency) is at 20kHz or (1/20000)sec, something which means low signal rate. I thought to use filters but these analog filters is extremely difficult to be...
Re: pll calibration
Thanks for your reply. My frequencies at the baseband are placed from about ~ 20Khz to 90kHz. This square signal is transmited from an rf module at 433.92 MHz. After transited i receive the original signal (20kHz to 90kHz) and these fraquencies i want to convert into...
I want to callibrate a pll(74HC4046AN) as part of an mfsk demodulator for my diploma thesis.
17 different frequencies which correspond to 17 different analog voltages get in the phase
comparator. The pll have to lock each time at different frequency. I have tryed any
combination for RC filter...
I 'm looking for books or any type of information about digital modulation (fsk,ask,qpsk etc) and especialy for m-fsk. I' m interested in spectrum they posses. I would expect any type of help....
thanks in advance
I' m currently implementing an mfsk modulator-demodulator and i want to use a rf module for the transmittion of data. The modules have to transmitt analog signals of the differend level (one level for each carrier). Is there anybody to propose any module for this implementation?
thanx
