If summing a ring tone and a phone signal, the phone signal should use a differential input signal while the ring
tone might be limited to a single-ended signal. Phone gain is set at gain 1 = 0.1 V/V, and the ring-tone gain is set
to gain 2 = 2 V/V, the resistor values would be…
RI1 = 3 M, and = RI2 = 150 k.
The high pass corner frequency of the single-ended input is set by CI2. If the desired corner frequency is less
than 20 Hz...
