2.4.4 Bandwidth

Default bandwidth is 20HZ.

Explanation:
1. The higher rate of bandwidth setting will lead to higher fluctuation in data
waveform. Conversely, the lower rate of bandwidth, data will become more
fluent.

For example:
Bandwidth as 50Hz, Output rate as 5Hz. The waveform is very steady.
