The correct Answer is:
To solve the question "The attenuation of a signal is compensated by," we need to follow these steps: ### Step 1: Understand the concept of attenuation - **Attenuation** refers to the loss of strength of a signal as it travels through a medium. This can occur due to various factors such as distance, interference, or the medium itself. ### Step 2: Identify the options given - The options provided are: 1. Rectifier 2. Oscillator 3. Modulator 4. Amplifier ### Step 3: Analyze each option - **Rectifier**: This device converts alternating current (AC) to direct current (DC). It does not compensate for signal loss. - **Oscillator**: This device generates a continuous wave signal. It is not used to compensate for attenuation. - **Modulator**: This device modifies a carrier signal to encode information. It does not address the issue of signal strength loss. - **Amplifier**: This device increases the strength (amplitude) of a signal. It is specifically designed to compensate for attenuation. ### Step 4: Conclude the correct answer - Based on the analysis, the correct answer is **Amplifier**. An amplifier is used to compensate for the attenuation of a signal by increasing its strength. ### Final Answer: The attenuation of a signal is compensated by **Amplifier**. ---

Assertion: Amplification is necessary to compensate for the attenualtion of the signal in communication system. Reason: Amplification is the process of increasing the amplitdue and consequently the strength of a signal using an electronic circuit.

(i) The intensity of a light pulse travelling along a communication channel decreases exponentially with distance x according to the relation I = I_0 e^(-alphax) , where I_0 is the intensity at x = 0 and alpha is the attenuation constant. Show that the intensity reduces by 75 percent after a distance of (ln 4)/(alpha) (ii) Attenuation of a signal can be expressed in decibel (dB) according to the relation dB = 10log_10 (I//I_0). What is the attenuation in dB//km for an optical fibre in which the intensity falls by 50 percent over a distance of 50 km?
