Preliminary specification
OM4031T
Filter characteristic
The frequency characteristic of the moving average filter in
the OM4031T is given in Fig.3 for N = 12 and N = 6.
The horizontal axis shows the normalized frequency fN
which is the ratio of the frequency f and the sampling
frequency fs. The value for fs is given in Table 1 for the
various data rates and filter bandwidths.
The vertical axis shows the normalized amplitude AN.
At normal bandwidth the oversampling rate is 16, except
for 4800 bits/s where it is 8. At double bandwidth the
oversampling rate is 32, except for 2400 bits/s,
where it is 16.
The 3 dB cut-off frequency is calculated as follows:
N = 12: fco = 0.0371 × fs
N = 6: fco = 0.0748 × fs
