Assertion (A): Binary phase shift keying (BPSK) is the most efficient ...
BPSK is the most efficient of the three digital modulation, i.e. ASK, FSK and PSK because BPSK is used for high bit rates. Reason is also a true statement but not the correct explanation of assertion.

Assertion (A): Binary phase shift keying (BPSK) is the most efficient ...
Answer:
Binary Phase Shift Keying (BPSK) is a digital modulation technique that uses two different phases of a sinusoidal carrier wave to represent binary information (0 and 1). The phase of the carrier wave is changed according to the data bit to be transmitted, resulting in a phase shift of either 0 degrees or 180 degrees.
Assertion (A): Binary phase shift keying (BPSK) is the most efficient of the three digital modulation techniques, i.e., ASK, FSK, and PSK.
Reason (R): In BPSK, the phase of the sinusoidal carrier is changed according to the data bit to be transmitted.
Explanation:
Efficiency of Digital Modulation Techniques:
The efficiency of a digital modulation technique refers to its ability to transmit the maximum amount of information (bits) per unit bandwidth or power. In other words, it measures how well a modulation scheme utilizes the available resources.
Types of Digital Modulation:
1. Amplitude Shift Keying (ASK): In ASK, the amplitude of the carrier wave is changed according to the data bit to be transmitted.
2. Frequency Shift Keying (FSK): In FSK, the frequency of the carrier wave is changed according to the data bit to be transmitted.
3. Phase Shift Keying (PSK): In PSK, the phase of the carrier wave is changed according to the data bit to be transmitted.
Comparison of BPSK with ASK and FSK:
1. BPSK vs ASK: BPSK is more efficient than ASK because it uses the phase of the carrier wave to represent binary information, which allows for a higher data rate and better spectral efficiency. ASK, on the other hand, uses the amplitude of the carrier wave, which is more susceptible to noise and interference.
2. BPSK vs FSK: BPSK is also more efficient than FSK because it uses the phase of the carrier wave, which allows for a higher data rate and better spectral efficiency. FSK, on the other hand, uses the frequency of the carrier wave, which requires a larger bandwidth to transmit the same amount of information.
Explanation of Assertion (A):
Binary Phase Shift Keying (BPSK) is indeed the most efficient of the three digital modulation techniques (ASK, FSK, and PSK). This is because BPSK uses the phase of the carrier wave to represent binary information, which allows for a higher data rate and better spectral efficiency compared to ASK and FSK.
Explanation of Reason (R):
The reason given for the assertion is correct. In BPSK, the phase of the sinusoidal carrier wave is changed according to the data bit to be transmitted. This means that a phase shift of either 0 degrees or 180 degrees is applied to the carrier wave, depending on whether the data bit is 0 or 1. By changing the phase of the carrier wave, BPSK is able to represent binary information.
Conclusion:
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct answer is option 'B' - Both A and R are true, but R is not the correct explanation of A.
