Advisory Committee Statement

Approval for two minor design changes to the ESPrit (ear level) speech processor: 1) the addition of a 47uF capacitor; and 2) the lowering of the crystal Q with insertion of a low value resistor (R3-120). As stated in the submission and described in the telephone conference on July 22, 1998, these two changes have been tested and validated. With reference to item 1), this change would lower the total harmonic distoriton resulting in improved audio signal. In item 2) you would improve the oscillator stability over a specified temperature range resulting in better production yield.
