Example
Here are some bandwidth and sample rate results using the “k” calculation for
bandwidth:
=====================================================================
Fs = 20.48 MHz default internal ADC clock
(all data in MHz)
=====================================================================
| Signal Bandwidth | Sample rate
sigBw | .25 dB | 15 dB | Decimate OFF | Decimate ON
________|_________|__________|________________|______________________
0 | 7.37 | 10.24 | 20.48 | 10.24 (see Caution)
1 | 3.69 | 5.12 | 20.48 | 10.24
