True, but remember that the maximum non-filtered output frequency from the CD is only 22050 Hz (with a sequence of two alternating output values). I don't believe that any CD will damp this frequency seriously (say, more than 50 percent). If the minimum and maximum output value are used, the signal ought to be strong enough. But the TTL convertor circuit should be designed so that it will work with a reasonably wide range of signal amplitude, so that it'd work also with players that only have a headphone output.
