Electrical Specifications
NOTE:
Ideal Equation
When the two filters are set to the same frequency and the input signal is present for the periods T
For example, assume 300mV
the Reference channel is programmed to a Gain of 0.188. The Knock channel is then automatically set to a gain of one. The input signal is contin-
uous for the total integration time, T
