[antispeed gun radar]

I have developed the perfect device to avoid being done by Radar guns. An amazing side shoot is that this also works on the old amphometer tapes on the road.

Anyone interested just respond here.

Hi there 8), sure we are interested, please let us see ur design ;D.

Thanx

[PC Oscilloscope"need help"]

hey guys  :D,

I am using my sound card as input port, for an osilloscope using a software.

My quistion is: ??? What is the maximum voltage or power I can apply?


Please help me,
Thanx.

[delta modulation IC]

Hi every body  ;D,

I am looking for an IC which does "delta modulation", I found some as data sheet but I could not buy thim cause they was not available in the shoping sites I know,  ??? can any one help me    :-[ Pleeeeeese  :-[

;D audioguru  :D Thanx man, you saved half of my life>

[collector dynamic ro (2N2222)]

Hi guys,

please I need to know the value of the collector dynamic resistance of the BJT NPN transistor of philips (2N2222) , I looked for it in the product data sheet but it wasn't there so please if any body have idea about it please tell me ( its urgent) also I need the beta.

thanx

[digital tranciever]

mettula & Alun, Thanx a lot:
actualy i'm planning to use crystal oscilator, but my need is the sampling rate needed to sample the voice of humen???

[digital tranciever]

Hi guys....

I'm working on a digital tranciever and I'm using OOK...
So can any body till me how can I calculate the values of th R&C in the envelope detector("I'm using a circuit of a diode connected in series with a parallerl R&C")[my frequency is 5MHz].

Also I need to know what clock speed I need for a delta modulation("I am using delta modulation and my frequency is the humen voice frequency"). ??? ???

Thanx ;D

[Transmitting Power??]

Thanx everybody I got some ideas from your replys, and I appreciate you all ;)

[Transmitting Power??]

:) ;D audioguru,prateeksikka and 4-1000A >>> Thank you very much for your response.

I believe I have to give more info. about my project to get help, so this is a brief summary about my project:

[Transmitting Power??]

:) Hi guys

Can any body till me how to calculate the power needed to transmit!!
>>>> I want to transmit a signal with a range of 400m , but I am not sure about the power??
