WebApr 2, 2024 · You are sampling three waves f 1 = 10 Hz, f 2 = 30 Hz, and f 3 = 70 Hz, with a sample frequency of F s = 1.5 × 70 Hz = 105 Hz. This means that your Nyquist frequency is F N = F s / 2 = 52.5 Hz, and corresponds to the maximum value of your frequency axis. WebJul 22, 2015 · When operating at its maximum sample rate, this device supports signals up through the second Nyquist zone. The ADS5463 is a 12-bit, 500MSPS ADC with an input bandwidth of 2GHz. When … WebAlias Frequency Nyquist frequency: fN = fs/2 = 1/(2δt) This represents a folding point for the aliasing phenomenon. All actual frequency content in the analog signal that is at frequencies above fN will appear as alias frequencies of less than fN; that is, such frequencies will be folded back and superimposed on the signal at lower frequencies. 駐車場禁止マーク
