Synchronicity of samples
Environmental specifications
In a Link chain configuration with
several analog modules the
sample synchronicity of all
modules depends on the
sampling frequencies of each
module. For sample synchronicity
the module sampling frequency
must be a multiplier of 2 to the
power of n (Fs x 2n; n = wholenumbered) of each other module
sampling frequency.
Example: One module sampling
frequency (Fs) = 4kHz. Sampling
frequency of all other modules
must be one of the following: 4kHz
x 20 (= 4kHz), 4kHz x 21 (= 8kHz),
4kHz x 22 (= 16kHz), 4kHz x 23
(= 32kHz), 4kHz x 24 (= 64kHz),
and so on; or 4kHz x 2-1 (= 2kHz),
4kHz x 2-2 (= 1kHz), 4kHz x 2-3
(= 0.5kHz), 4kHz x 2-4
(= 0.25kHz), and so on.
