You wish to use an 8-bit A/D converter with Vref = 5 V to measure a signal (amplitude = 2 Vpp, frequency = 1 kHz) that includes substantial noise (amplitude ≤ 0.5 Vpp, frequency = 5 kHz). What is the minimum sampling frequency required to ensure that aliasing will not inhibit your ability to accurately interpret the data? What would you do to prevent the high frequency noise from affecting your readings if you do not want to sample at such a hig

    The answer is explained below for the sampling frequency

    Explanation:

    Solution

    Recall that:

    The frequency Fm1 = 1 kHz

    The frequency Fm2 = 5 kHz

    Fs = n (2Fm2)

    so,

    [Fs = 8 * (2 * 5) = 80 8kHz], This the sampling frequency for 8-bit A/D converter

    Now,

    By increasing quantization level we can also increase the substantial noise ratio
