Optical Tachometer Provides BiDirectional Info - 05/21/98 EDN-Design
Ideas....Many systems, especially communications, require AGC that functions
at 50 MHz. Self-calibrating systems, such as automatic test equipment, need
this high-frequency response but also require digital control of the AGC
output voltage. During the calibration cycle, the test equipment calculates
the AGC output voltage necessary to achieve....file has several circuits,

Simple circuit measures diesel's rotations per minute - 03/04/99
Issue of EDN You may find it useful to measure a diesel engine's
rotations per minute to accurately adjust the idling or to compare the
motor's speed under hot and cold conditions, for example. Not all cars or
trucks come with a tachometer. The scheme in Figures 1 and 2 allows you to
measure....Page includes several designs. Scroll to find this one....(EDN

Tachometer Demodulator has Fast Response Time - 12/07/95 EDN-Design
Ideas....When a tachometer is a critical part of overspeed-shutdown circuitry, the
response time of conventional demodulators may be too long. The circuit in the block
diagram in Figure 1 provides updated speed data. The circuit provides corrections for
variations in excitation amplitude and frequency at every excitation half-cycle. The
circuit is independent of processors and, therefore, immune to softwareand bus-related
failures.... EDN is migrating links. This link is not verified. Google the

Tachometer for Bikes (circuit) - Here are some instructions how to connect
the Tachometer version II to a single cylinder. (design added 3/07) |
|
Tachometer/RPM - Easy to build using only a few components. With some
modifications, it can be used in an automovil. This Tachometer uses a PIC
16F628.(design added 06/04) |
