| List I | List II | ||
| A | AM Broadcast | I | 88-108 MHz |
| B | FM Broadcast | II | 540-1600 kHz |
| C | Television | III | 3.7-4.2 GHz |
| D | Satellite Communication | IV | 54 MHz-890 MHz |
Choose the correct answer from the options given below:
AM Broadast \(→\) 540−1600 KHz
FM Broadcast \(→\) 88−108 MHz
Television \(→\) 54−890 MHz
Salellite communication \(→\) 3.7−4.2 GHz
So, the correct option is (B): A-II, B-I, C-IV, D-III.
Match List-I with List-II:
| List-I (Modulation Schemes) | List-II (Wave Expressions) |
|---|---|
| (A) Amplitude Modulation | (I) \( x(t) = A\cos(\omega_c t + k m(t)) \) |
| (B) Phase Modulation | (II) \( x(t) = A\cos(\omega_c t + k \int m(t)dt) \) |
| (C) Frequency Modulation | (III) \( x(t) = A + m(t)\cos(\omega_c t) \) |
| (D) DSB-SC Modulation | (IV) \( x(t) = m(t)\cos(\omega_c t) \) |

Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).
The magnitude of heat exchanged by a system for the given cyclic process ABC (as shown in the figure) is (in SI units):

A system that describes the information exchange between two points is called the communication system. The transmission and reception process of information is called communication. The major elements of communication are such as:
The following are the examples of communication systems:
Turning on Signal specification or technology, the communication system is categorized as follows:
