particle slope forms an S curve at this part of the slope, with three sizes of particles
giving the same signal; in less severe cases, the signal goes flat, with no significant
difference in pulse height between, say, a 1



m and a 2



m particle. Climet’s design

has a monotonic response across the entire range of measurement.

4.2.4

The electronic subsystems

The electronic system begins with the semiconductor detector that produces an
electrical current that is proportional to the amount of light scattered by the particle,
and thus proportional to the size of the particle. Amplifier and signal processing
circuits amplify the signal, and attenuate background noise, which allows smaller
particles to be detected. The CI-154 uses patented (5,870,190) Digital Signal
Processor (DSP) circuitry to electronically sort these pulses and set threshold
voltages.
