When The center frequency is tuned to 95.5 MHz where is all most no other FM stations in the spectrum analyzer span. The RF gain is set to 13 for best signal to noise ratio across the FM band. The sample rate is set to 1.024 MS/s which provides 2.024 MHz span.

The sample rate is set to 1.024 MS/s which provides 2.024 MHz span. The Threshold Calculator enables you to use sample data from your operational server database to calculate the appropriate Clerical Review and Auto-link thresholds. Based on the weights files you generated, the Threshold calculator generates a ROC curve. A ROC curve (Receiver Operating Characteristic curve) is a plot of true positive rate

hardware will collect in a unit of time (normally seconds or minutes). The BSL software stores these amplitude values as a string of numbers. Since the sample rate of the data is also stored, the software can reconstruct the waveform. 4 -10 -5 0 5 10 15 20 0 0.2 0.4 0.6 0.8 1 Time index n Amplitude ADVANCED Unit Step Sequence Project 1.2 Exponential signals A copy of Programs P1_2 and P1_3 are given below.

The sample rate is set to 1.024 MS/s which provides 2.024 MHz span. The sampling rate is important for determining the maximum amplitude and correct waveform of the signal as shown in Figure 2. Figure 2: In the top graph, the 10 Hertz sine wave sampled at 1000 samples/second has correct amplitude and waveform. In the other plots, lower sample rates do not yield the correct amplitude nor shape of the sine wave

Short answer. Assume that the signal is sampled (at least) by the Nyquist frequency, the number of samples is N and that the sampling time is T0 seconds. Then the sampling interval is T = T0 /N Then you'll have frequencies ranging in 1/T0 , 13/09/2016В В· I am trying to extract amplitude array from an audio file(WAV file).

The sample rate is how many samples, or measurements, of the sound are taken each second. The more samples that are taken, the more detail about where the waves rise and fall is recorded and the 30/06/2013В В· I want to know the relation between sampling frequency (Hz) and sampling rate (sample per second). For example, a 1 Hz sin wave sampled at 8000 samples per second. Each cycle of the 1Hz tone will span all 8000 samples (since its period is 1 second). Thus sampling period will be 1/ (8000-1) s Or sampling frequency will be 8000-1 в‰€ 8000Hz.
