8051 board..
hi all,
does anybody have any docs/ shchematics/ tutorial on how to built an evaluation/ prototyping board with 8051 microcontroller? oh by the way, the programmer as well..
thanks :)
hi all,
i'm trying to build my own solar energy system. the thing is, i don't have any idea how :P i knew (long time ago since i was 10) that the energy from the sun can be converted to electrical energy. i've been trying to access to some practical design methodology for this purpose but...
articles involving reed
hi all,
i dunno where should i put this request, but i think it does relates to RF somehow. i'm actually looking for these article:
I. Chlamtac and A. Farago, “Making Transmission Schedules Immune to Topology Changes in
Multi-Hop Packet Radio Networks”
D. V...
reed solomon for small data?
thanks zorro and flautulent for your guys feedback.
i came across a topic saying that reed-solomon is one of the way to avoid collision in one way communication. what i knew was reed-solomon is used for data storage esp. on CD. anyway, if you guys have tried to...
transformer coupled nrz matlab
hi all,
i do need help on my project. i've been building an simple RF system but i need some method:
1) to proof that manchester coding is better than NRZ. some mathematical model/ simulation might help and clarify more.
2) probability test upon the codes...
mutoucanada.. i do need the 50% duty cycle.
i've tried to use hystheresis (using different circuit than above) and it can produce the 50% duty cycle (almost perfect 90 degree up/down) but the top/ bottom portion of the wave have jitters. does anybody know how to cut-off this portion?
the...
help:design clock 4MHz
hi, i hope that somebody can help me/ give suggestion how can i achieve a 4MHz square wave from a 20MHz crystal and CMOS inverters.. or if you have a better way to do it, that is most welcome :D
i've tried to use 4MHz crystal but the produced waveform is not exactly...
