Frequency Detection
When two sinusoidal signals of the same amplitude and slightly different frequencies are added together, a beat frequency is produced. The beat frequency is equal to the difference between the two frequencies. In this case, the beat frequency is 100 Hz (10.1 kHz - 10 kHz = 0.1 kHz = 100 Hz).
Ideal Frequency Detector
An ideal frequency detector is a circuit that produces an output signal that is proportional to the frequency of the input signal. In other words, if the input signal has a frequency of 10 kHz, the output signal will be proportional to 10 kHz. If the input signal has a frequency of 10.1 kHz, the output signal will be proportional to 10.1 kHz.
Output of the Detector
In this case, the combined signal has a beat frequency of 100 Hz. When this signal is given to an ideal frequency detector, the output will be proportional to the frequency of the input signal, which is 10.1 kHz. Therefore, the output of the detector will be a 10.1 kHz sinusoidal signal.
Answer
Option B is the correct answer, which states that the output of the detector is a 10.1 kHz sinusoidal signal.
When two sinusoidal signals of the same amplitude and slightly different frequencies are added together, a beat frequency is produced. The beat frequency is equal to the difference between the two frequencies. In this case, the beat frequency is 100 Hz (10.1 kHz - 10 kHz = 0.1 kHz = 100 Hz).

In other words, if the input signal has a frequency of 10 kHz, the output signal will be proportional to 10 kHz. If the input signal has a frequency of 10.1 kHz, the output signal will be proportional to 10.1 kHz.
Output of the Detector
In this case, the combined signal has a beat frequency of 100 Hz. When this signal is given to an ideal frequency detector, the output will be proportional to the frequency of the input signal, which is 10.1 kHz. Therefore, the output of the detector will be a 10.1 kHz sinusoidal signal.
Answer
Option B is the correct answer, which states that the output of the detector is a 10.1 kHz sinusoidal signal.
