waves sinusoidalis
Sine waves are used because in liner circuits the effect on them can be only phase variation and hence the signal isn't distorted
regarding system response sine waves are not optimal for that but delta function is
cordless and cellular?
Compy
The GSM is the standard used in Europe for Cellular(mobile) communication and it uses the TDMA and FDMA techonolgies for making calls
CDMA is the equivalent system for GSM but in North America however this system works in a different way using what is called...
Re: Why we use MOS family?
sorry but i guess bjt is a majority carrier device as NPN carriers are electrons while mos is minor carrier since we make a channel opposite to kind of used SC like n-channel
Re: Why we use MOS family?
Bjt is better than mos in both gain and BW
it's also faster
but the mos advances bjt in
it's very high input impedance due to the use of oxide
it's easy fabrication and easy scaling technology that makes its speed very high and near to bjt
lower cost
low power...
Re: class c
class c is a common emitter amplifier works in off region and needs only ac signal to let it operate on/off and according to application needed it's usually used in AM
Re: Build network help
however using coaxial is bad choice since it's speed is very low compared to cat 5 also it's not assured about it performance or easy to connect
designing amplifiers depend mainly on some assumptions where for a Common emitter as an example
u can assume that current in universal divider = 10 and 11 * (base current)
and Volt on emitter resistance = 0.1 Vcc
and Vce = 0.5 Vcc
but these assumptions mainly depend on the number of unknowns u...
