Abstract
A system and method of generating a synthetic time period output signal for a fork density sensor (601) which produces a consistent and low-noise output signal (705) which is identical in frequency to the frequency at which the fork density meter vibrates. Such a synthetic signal generated by a meter signal prevents any real noise from the pickoffs from propagating to the output meter and removes process noise and interference from the produced output signal.
Claims15
A method of generating a time period output signal, the method comprising:
- receiving a signal from a meter (601);
- filtering (608) the signal;
- synthesizing (610) an analog synthesized filtered signal based on the filtered signal;
- and
- inputting the analog synthesized filtered signal (604) into a drive circuitry (611) and an output circuit;
- generating, with the output circuit, the time period output signal (606) from the analog synthesized filtered signal (604).

A method of generating a synthetic time period output signal, comprising:
- receiving a pickoff signal from a fork density sensor meter (701);
- filtering the pickoff signal (702);
- synthesizing the filtered analog pickoff signal (704) to create an analog drive signal;
- and
- inputting the analog drive signal into a drive circuitry to generate a drive signal and into an output circuit to generate a time period output signal.
