The above figure shows a cross-over network in a loud speaker system. One branch consists of a capacitor $C$ and a resistor $R$ in series $($the tweeter$).$ This branch is in parallel with a second branch $($The woofer$)$ that consists of an. inductor $L$ and a resistor $R$ in series. The same source voltage with angular frequency $\omega ($from an amplifier$)$ is applied across each parallel branch.
The radio altimeter on an aircraft is a
An amplifier is required in the process of detection of a signal because:
Full motion video requires an enormous bandwidth of 12 Mbps. true=1, false = 0
When m = 1, power carried by side bands is:
