.SH DESCRIPTION
Unfortunately, the analog anti-alias filters can't be disabled on any
input or source channels in the E143x modules.  Originally this
function was going to be used to disable the analog anti-alias
filters, but now this function is essentially useless.

See \fIe1432_set_anti_alias_digital\fR for disabling the digital
anti-alias filters, which \fBcan\fR be done.

If this function is called, the parameters must obey the following:

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of channels that was obtained by a
call to \fIe1432_create_channel_group\fR, or the ID of a single channel.

\fIstate\fR must be set to \fBE1432_ANTI_ALIAS_ANALOG_ON\fR, otherwise
an error is generated.
.SH "RESET VALUE"
After a reset, \fIstate\fR is set to \fBE1432_ANTI_ALIAS_ANALOG_ON\fR.
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
