Does anybody have any ideas or recent research in the field of synthesis of analog blocks like PLLs/memories?

hi jawad !
already available in market,manual u will get along with that and hence ur report!

does that help?

if i am asked to make it ,i would make a simple relay .other's comments r welcome!

IF it is software controlled ,you can add a single statement to set 1 bit after 1hour (say n clock cycles)

n u can calculate given your clock freq.this set bit can be used to drive a relay permanetly ,if high the relay will be on ....
thats it

u can succeed if u convert the output count to a clock generator i mean a glue logic like an and gate before a clockgen  ....
and feed the clock to say a relay....
no of clocks = no of vibrations!!!

sorry for not solving your problem.but could u please tell me what a megaphone is?

that was nice .but i dont get where is windows being used as speakers in this case..?

for such a case ,it depends on the frequency respose you want .
Inductance L is proportional to the number of turns you give to the coil ...
Although it is  a theoretical thing ,pracically it also depends on the material of the coil...

hi audioguru!

Can you tell me what will hapen if we try to Frequency modulate both sound and picture in a TV unlike AM for video .I was just kind of experimenting with this ...
have u ever tried this in past?

i dont think frequency is the criteria .
it is just the question of current carrying capability.

ill definitely share an experience here .
i tried pulling out an IC once from my board by heating the chip till it melts .
i discovered it may affect the neighbouring devices as they may get overheated .if u hv not put the neighbouring chips ,perhaps u can melt the plastic using solder iron

hi saiello.

i myself have not used it but have seen people using it.
this is a very compact and easy way of printing the circuits but i personally dont recommend it just because of the fact that i see a possibility of the tracks getting shorted down even if a bit of ink spreads specially if tracks are closely spaced.

electroni principles by Malvino or the book by Robert R.Boylestead are good for filters

just an update .dont forget  theres no negative resistance its imaginary.......part only
