XR2206 ic vs normal func. gen

[Lory]

Hi,

The sine waves in my XR2206 IC function generator started
at 3 volts and varied from there to 5 volts and 1 volt.

In ordinary function generator equipment. Is the
sine wave at 0 volts and rising/falling from it or
does it also start at higher voltage as base?

My function generator allows me to offset the signal by a variable amount,
both pos. & neg. I think it may be based on the XR2206, but I'm not
certain.

It depends on whether the designer made it one or the other. If the output
is couple with a capacitor there is no DC offset, so the sine wave varies
around 0V. If a DC offset is superimposed then the output will vary around
that.

-----------
Put it through an inline capacitor and it will be referenced to 0
as long as it is a sine and is buffered by an amp after it. Then
you can add an op-amp adder stage to add any DC offset to it that
you wish.
