Role of Power Metric and LPF in AGC(Automatic Gain Controller)

Web6 mei 2024 · How fast must the filter "roll off"? Generally filtering for an ADC is to reduce the effects of aliasing. Aliasing occurs when a frequency above the Nyquist frequency (sample rate / 2) is input to the ADC. So an anti-aliasing filter is a low pass filter with a cut off near the Nyquist frequency. http://www.wirelesscommunication.nl/reference/pdfandps/qam.pdf mortgage post closing training
