For the following questions answer them individually
The line of sight communication requires transmit and receive antenna to face each other. If the transmit antenna is vertically polarized, for the best reception the receive
antenna should be:
A network contains linear resistance and ideal voltage source. If the value of all the resistors are doubled, then the voltage across each resistor is:
Twelve 1 ohm resistances are used as edge to form a cube. The resistance between two diagonally opposite corners of the cube is:
An eight bit digital data 10101100 is fed to an ADC. The reference voltage is +10V. The analog output voltage will be:
A series RLC circuit has a resonant frequency of 1 KHz and a quality factor Q = 100. If each of the R,L and C is doubled from its original value, the new Q of the circuit is:
The input to a coherent detector is DSB-SC signal plus noise. The noise at the detector output is:
Gunn diode is a:
The intrinsic carrier concentration of silicon sample at $$300^\circ K$$ is $$2.5 \times 10^{16} /m^3$$. If after doping, the number of majority carriers is $$5 \times 10^{20} /m^3$$ , the minority carrier density is:
The unit of $$\triangledown \times H$$ is:
A PIN diode is:
