Q. Explain about Frequency Shift Keying?
In this scheme frequency of the carrier signal is changed according to the data. Transmitter sends different frequencies for a "I" than for a "0" as displayed in Figure. Disadvantages of this technique are that again (as it was with amplitude modulation) the rate of frequency changes is limited by bandwidth of the line and that distortion caused by the lines makes detection even harder than amplitude modulation.
Draw and explain the block diagram of DMA controller. The fundamental idea of DMA is to transfer blocks of data directly between peripherals and memory. The data don't suffer t
Fermi Level Electrons in solids obey Fermi-Dirac (FD) statistics. This statistics accounts for the indistinguishability of the electrons, their wave nature, and the
Q. Explain the significance of the Coupling capacitor and the RE - CE circuit. The function of the coupling capacitor is to isolate the amplifier input circuit from the source.
What is basic requirement of semiconductor laser? Draw its label diagram and explain its working with necessary theory. Write down the applications of semiconductor laser.
a. The antenna current of an AM broadcast transmitter, modulated to depth of 40% by an audio sine wave is 11 amp. It enhances to 12 amp as a result of simultaneous modulation by an
Q. In an AM transmitter that transmits a total power of 1 kW, the unmodulated carrier power is 850 W. Compute the required value of (S i /N i )AM at a receiver, if (S 0 /N 0 )AM
