Applications

* such as the tonegeneration portion of a test stimulus for CPM circuits. Figure 1. In this tone generator, the uncommitted op amp of the lowpass filter IC1 acts as a summing amplifier. The amplifier's gain level assures that 5V-logic inputs will not cause clipping at the two-tone output. Generating
