baising
hi every one
i had searched a about the idea of biasing the transistor in the common emitter circuit
i had read different ways but am little confused about something that i want to ask about
1) I read about the q-point at which he transistor must be set at dc operation before...
please i would like anyone to help me about the basics of designing the simple amplifier circuits by using the transistors>>mention the input impediance and the output impediance and gain and the base current and all things like that please simple explaination and if drawing it would be better
question about lm386
1) what is the maximam frequancy the lm386 can amplify with good gain...
2) i made the amplyfying circuit by lm386 and grounded the inverting input and by 1uf capacitore i connected it to mic....the other leg of the mic is grounded .....i didn't hear my voice what is the...
isd100a
hi... i would like to ask you some thing
is the pinout of ISD25120 the same of the pinout of ISD100A......
in other words...can i replace ISD100A by ISD25120 for more record time?
please i want the law used to make a coil with certain impediance
by determining the thickness of the wire, the radius of the core, the kind if the core,
the length of coil .......please i want this with drawing if available...if not available the formula is ok
please i want your reply in...
Re: 555 Timers
YOU CAN SEE THIS PAGE:
**broken link removed**
IT EXPLAINS THE 555 THEN IT GIVE YOU SOME FORMULA FOR WHAT YOU WANT WITH DRAWING
I TRIED TO USE THOSE FORMULA PRACTICALLY AND IT WAS FULLY SUCCEEDED
ALSO TO HAVE ACCURATE RESULTS YOU HAVE TO CONNECT THE 555 TO +5V NOT MORE OR...
ok thanks
but
in the first websit you had given to me:
i know the function of the pins but i would like to ask you some questions because i am litte confused,,,,please be patient with me
1)at pin 4 ,,, if it is connect it means keeping the data and disconnecting it means not keeping the data...
hi....all
i wish you are fine
please i would like to help me in learning how to prgram the microcontroller from A to Z including the device used to write on it throught the computer also how to read it and how to program it with vb or assembly with drawing and full explainations in...
calculating pulse number
hey............
how are you all,,,,,,,,,,i wish you are fine
i would like to ask you a question:
how can i calculate the number of pulses comming continously one after one at one second then if the number of pulses are 1000 pulse in second (for example)how can then i...
