    Question

    If receiver noise floor is 2 dB, signal-to-noise ratio

    is 3 dB then what is the receiver sensitivity?
    A 1 dB Correct Answer Incorrect Answer
    B 5 dB Correct Answer Incorrect Answer
    C 2 dB Correct Answer Incorrect Answer
    D -1 dB Correct Answer Incorrect Answer

    Solution

    Receiver sensitivity is defined as the  minimum input signal power  required by the receiver to achieve a specified  signal-to-noise ratio (SNR)  at the output. Mathematically,
    Receiver Sensitivity = Noise Floor + Required SNR Here, Noise Floor = 2 dB SNR = 3 dB So, Receiver Sensitivity = 2 dB + 3 dB = 5 dB
