Automatic curve horn

Posted: 26 Sep 2010 02:41 AM PDT

hi CEans,
i am 3 year mechanical engineering student,i got one idea in automatic horn when takeplace curve position in roads, hillstation while vehicles in running.

This horn very useful in curve position of accident zone, hillstation, night time driving .

we had think varible resistance is placed in steering and while taking any sensors
for judging curve position its automatically takes horn.

we placed any digital circuit for seeing whats the angle that curve takes,for that we adjusting curve angle for eg.30 and 40 degree

this is my small idea please give your opinion .i am waiting for your comments

thank you

Basics of differential amplifier

Hi

In a single ended double output diff amp, one of the i/ps is grounded. Can somebody tell me how the Ic flows through the transistor when the base is at zero voltage?

Regards
Brittoo
