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

PLEASE HELP ME(PH METER)
prateeksikka replied to M.JAWAD's topic in Electronic Projects Design/Ideas
hi jawad ! already available in market,manual u will get along with that and hence ur report! http://www.pgiinc.com/digelphmet.html does that help? -
if i am asked to make it ,i would make a simple relay .other's comments r welcome!

adding sound to a clock
prateeksikka replied to interested's topic in Electronic Projects Design/Ideas
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 -
Device for blind people question
prateeksikka replied to sonictronic's topic in Electronic Projects Design/Ideas
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!!! -
need Megaphone circuit?
prateeksikka replied to necrophilic_coder's topic in Electronic Projects Design/Ideas
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

i wish to join IEEE.Does any one know how to do so? What member ship grade i qualify for if i serve in an industry after graduation in electronics(6 months ago)

hi audioguru! can i run my 220V indian device in Canada where 120V is the mains supply or like wise in any other country where we have only 120V? is a step down transformer enough for this?
-
u may also use a calibration equipment (apparent freq)... while here in india FM range is 88-108MHZ .whats in ur case?

i guess at such low voltage level at which you are operating ,u do not need an optocoupler...i generally use it when there is a high voltage AC circuit on 1 side and a very low voltage dc ckt on the other...

silicon controlled rectifier
prateeksikka replied to abhishek gupta's topic in Electronics chit chat
why do u need to add? i visualize SCR as nothing but a controlled transistor and transistor as nothing but a controlled diode .... -
hi audioguru! even if we consider a diode as a capacitor in this reference ,what happens when we short circuit the ends of a capacitor? will it not get discharged?why wont the electrons on n side move to holes on p side through the external wire?
-
HI. My question is i have an open diode (not in any circuit) .I short its two terminals . Will the current flow through the wire for first few nano seconds to equalize p and n carriers?
-
hi.so what is the conclusion? will the current flow through the short?if yes ,the diode will get depleted of its charge carriers and it will be destroyed .no? what do u think?
-
As per my guidance you can take ORCADLITE by CADENCE DESIGN SYSTEMS latest version of 9.0 is now available . U can design as well as simulate.... ;D
-
Hi all. I want to know ,what will happen if we short the 2 terminals of a diode? will the current flow? what i suspect: Current will flow for some time till charge concentrations equate and diode is destroyed ..... i.e its functionality gets over....
