what is the significance of using Inverting Op-amp instead of using Non-Inverting Op-amp?
Does it realy makes any difference in amplification or what else?
In one the design i found that, Inverting op-amp was used: +ve pin was grounded & -ve volatge was provided at -ve pin to get o/p in +ve...
i have to change analog signal to differential signal and make it compatible with RS422 standard of communication. can anybody help. this is to be done using A/D converter i.e. first to convert analog signal to digital signal and this signal to make compatible with RS422 standard.
pnp transistor operation
i want to know the operation of PNP- actually its supply connections & current flow in comparison with NPN transistor. Please do specify the voltage & current relations with proper notations & +/- labels.
thanks in advance
noise
what is noise - of course unwanted data or any disturbance - but what actually creates noise eg. there comes interference between two FM stations - however their carrier frequencies are different but still the FM channel gets interference? It's true that it can happen due atmosphereic...
microcontroller input protection
how a microcontroller can be protected by voltage surges or spikes irrespective of use of regulated power supply - also regulators used in power supply have diodes in reverse? so what components to be used for protection of microcontrollers - using simple...
Why do voltage drop happen when length of connecting wire is more e.g. if i have 12Vdc output and i want to connect to some device at a distance voltage gets drop, i know this happens but why?/ and what is solution to drive 12Vdc upto a certain distance??? please help
