If B 7 and B 6 bits of mode register in 8237 are set to 11, which mode of operation is selected? For a bit-rate of 8 Kbps, the best possible values of the transmitted frequencies in a coherent binary FSK system are The drain of an N-channel MOSFET is shorted to the gate such that V GS = V DS . The threshold voltage (V T ) of MOSFET is 1 volt. If the drain current (I D ) is 1 mA for V GS = 2 V, then for V GS = 3 V, the drain current I D is- What is refraction? How is the damping ratio 'ξ' and quality factor 'Q' of a series RLC circuit are related to each other-
