This is a Multiple Choice Questions as classified in NCERT Exemplar

Answer- a

Frequency of career signal = 1MHz and frequency = 3KHz= 0.003MHz

So frequency of side bands = 1 $?$ 0.003

So 1.003MHz and 0.997MHz

A1 kW signal is transmitted using a communication channel which provides attenuation at the rate of -2dB per km. If the communication channel has a total length of 5 km, the power of the signal received is [gain in d_B=10 log₁₀(p₀/p_i)]
(a) 900 W (b) 100 W (c) 990 W (d) 1010 W

This is a Multiple Choice Questions as classified in NCERT Exemplar

Answer-b

p = 1kW= 1000W

Attenuation of signal = -2dB/km and total path length = 5km

Gain in dB= 5 $* - 2 = - 10 d B$

Gain in dB= 10 log (p₀/pi)……. (i)

-10=10 log (p₀/pi)= -10log (p_i/p_o)

logP_i/p_o=1 = log (p_i/p_o)= log10

pi/p₀=10= 1000W= 10p₀

p₀=100W

In amplitude modulated wave side frequency contain the information and from the question the power will be ω_c, (ω_c – ω_m) and (ω_c + ω_m)

So to minimise cost of radiation we use both (ω_c – ω_m) and (ω_c + ω_m)

The maximum frequency for reflection of sky waves from a certain layer of the ionosphere is found to be f_max= 9(N_max)^1/2, where N_maxis the maximum electron density at that layer of the ionosphere.
On a certain day it is observed that signals of frequencies higher than 5 MHz are not received by reflection from the F₁ layer of the ionosphere while signals of frequencies higher than 8 MHz are not received by reflection from the F₂ layer of the ionosphere. Estimate the maximum electron densities of the F₁ and F₂ layers on that day.

Frequency, fmax= 9 (N_max)^1/2

For F1 layer frequency is 5MHz

So 5 $* 10^{6} = 9 (N m a x)$ ^1/2

Nmax= (5/9 $* 10^{6}$ )²= 3.086 $*$ 10¹¹/m³

For F2 layer 8MHz

8 $* 10^{6} = 9 (N m a x)$ ^1/2

Nmax= (8/9 $* 10^{6}$ )²= 7.9 $*$ 10¹¹/m³

If the whole earth is to be connected by LOS communication using space waves (no restriction of antenna size or tower height), what is the minimum number of antennas required? Calculate the tower height of these antennas in terms of earth’s radius.?

Contributor-Level 10

This is a Short Answer Type Questions as classified in NCERT Exemplar

maximun distance to cover entire surface of earth for communication is

d_m²= (R+h)²+ (R+h)²= 2 (R+h)²

So d_m= $\sqrt[]{2 h R} + \sqrt[]{2 h R} = 2 \sqrt[]{2 h R}$

8hR= R²+2Rh+h²

R-h=0

R=h so frequency of space wave Is less than height of tower. So it is also keep in consideration. for 3 dimension coverage 2 antennna each side means total 6 antenna required.
