The sampling rate under samples this high frequency and creates a low (aliased) frequency equal to the high frequency minus sampling frequency. Thanks. In choosing the Fmax, we also set other parameters. Set Frequency in KHz: adb shell su -c "echo "702000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"//min frequencyadb shell su -c "echo "384000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq" //MAX frequencyadb shell su -c "echo "384000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq". But if the signal starts at a frequency other than near DC, then the minimum sampling rate need only be twice the bandwidth. where: f is the frequency in Hz p is the period in seconds (the amount of time required to complete 1 cycle) Knowledge of this relationship permits the determination of frequency components from the raw waveform data. com The natural frequency, or fundamental frequency, often referred to simply as the fundamental, is defined as the lowest frequency of a periodic waveform. class tftb. Journal compilation C 2008 RAS, MNRAS 385, 1279–1285 PLL, the phase comparator compares the phase and frequency of the signal input with fMAX. 813 Hz) G3 (195. The clock frequency = 333 MHz. fmax frequency
