Hi there
i would like suggestions on both the polarity detectors. As for the input range to the polarity detector, do you mean the range within which it detects the signal as positve, negative or zero? i would like the range to be as low as possible. the motor should coast to a stop with...
Can anyone suggest to me a simple circuit constructed using digital gates for polarity detection? The circuit should be able to detect positive, negative as well as zero polarity.
I need to check the polarity of a dc motor which is controlled by a bidirectional converter. The bidirectional...
Hi there.
I appreciate your reply. but the fact is i haven't started or done anything regarding this. i was just reading material on this but my concepts arent clear still. with ur help i might be able to go a long way in this project. pls start off for me. i ll get an idea and can carry on...
Hi there.
I am working on a study-oriented university project on digital modulation techniques. I am trying to implement a scheme of early-late gate synchronizer to latch on to the pulse instant. Can you help me with the different ways of doing it? along with any suitable analysis and...
Hi there.
No, this is not a homework or coursework. This is a study-oriented university project i am carrying out on digital modulation techniques. I am getting stuck on this derivation part where we assume random data from BPSK. Can u pls help me derive the equation and hence plot the power...
Hi there.
Thanks a lot for the reply jbunnii.
I understood your point regarding this. can u show me how do i generate this equation using a random data / vector without simulation? i mean mathematically can u derive the equation for me using random data bits?
i will highly appreciate...
Thanks a lot Dave and belliott.
Yes, i meant the 64 outcomes of the die roll of a six-sided die. Can you help me obtain this using the laws of probability?

Hi there
Thanks for the reply. When i said i wanted to obtain it, yes, i really meant deriving the equation of the power spectral density function and also plot the function using MATLAB simulation from the random data of BPSK.
Can you help me regarding this?

Hi there,
I am trying to obtain the waveform due to random binary phase-shift keying. the graph is similar to a sinc/sampling function. Can someone help how to go about it?

hi there,
i am trying a project on home automation through a telephone. i am trying to design my own system for this. can u give me some ideas regarding this? any site i should refer? any journal papers i can refer?
what is the simulation software i should know for designing this system...
hi there,
thank u for the reply..
i have more queries. what are the parameters do i consider while making a lift? how do i determine the wall thickness, platform height and total load capacity? is there some software for designing these? and how do i design these using software?
if u...
Hi there,
i am making an elevator design driven by a microcontroller. i am an electronics student and hence i am not able to get the mechanical design aspect of the elevator.
can anyone explain to me how to design the mechanical aspect of the elevator? what are the components for braking...
how does one perform a frequency sweep to obtain resonant frequency?
for instance, if the inductance is 50mH and the capacitance is 20nF, how do I achieve a resonant frequency of 200khz? what parameters are involved?
