1. ### how to put a 30khz 12vpp on 220 ac?

hi all i generated a pulse with 30khz and 12 volt pick to peak and i want to put it on main ac 220 volt. i dont have any idea for safety my circuit.what can i do?
2. ### relation between micro frequancy and calculate fft time?

i konw DSPs are optimize .but i have seen some project that use pic18f with my speed.as i searched for best performance with low speed micro that has hardware multipelier , u have to write assembly code not C or sth else.for floating point u need more speed because micro has special algorithm to...
3. ### relation between micro frequancy and calculate fft time?

hi all i want to find relation between micro frequancy and calculate fft time for choosing best micro for varities of fft.for example if i have a sampling rate 1Mhz with 256 lenght of sample.what speed is optimize for choosing micro controller.? i need to some formula.
4. ### how to enable hardware Multiplier in xmega?

u r right tnx
5. ### guess my algorithm (fft algorithm or sth else)?

hi fvm i read its datasheet and know it has a hardware multiplier .now can it perform the FFT in real time?or not?
6. ### guess my algorithm (fft algorithm or sth else)?

i know fft specification but i want to know that its posibble with this 8bit micro with this speed or not?
7. ### how to enable hardware Multiplier in xmega?

i want to enable hardware Multiplier with codevision.
8. ### guess my algorithm (fft algorithm or sth else)?

hi guys i have a black box that its output is like fft algorithm.but im absolutly confused because it use a 8bit pic microcontroller(pic18f252)with this specifications: sampling pulse is 1Mhz numbers of data is 256 as i think for this fft u need to a fast micro for lossless data.????? i think it...
9. ### compression algorithm code for hex array data?

my friend i asked from u not web link.as i said first of all i have to know algorithm then code. anyway i got it with youtube. tanks for ur time. i like rio
10. ### compression algorithm code for hex array data?

first of all i want to know that algorithm .i dont need to c code .i try to know it but i couldnt.can u explain it step by step?
11. ### compression algorithm code for hex array data?

ok i heard about that.but i cant underestand it. can u explain it on for example an array with 20 byte
12. ### compression algorithm code for hex array data?

compression algorithm code for hex array data? i have 500kbyte data. i want to decrease it to 50kb then send it and after Receive data decoding that without lost data .is it possible? i need to c code for my algorithm. please help me
