The 9V battery strainmeter signal adjusting circuit

Published:2011/6/20 22:21:00 Author:Seven | Keyword: 9V battery, strainmeter signal

The 9V battery strainmeter signal adjusting circuit is shown as above.Notes: this is a 9V battery strainmeter signal adjusting circuit, the sampling circuit offers the low average working current of 650μA. As ΔV/ΔT jumps in a high order, the RC net composed of 4.7KΩ and 0.01μF is used to protect the reaction bridge, which avoids the long-term drifting. (View)

The data general control circuit

Published:2011/6/20 22:17:00 Author:Seven | Keyword: data, general control

The data general control circuit is shown as above. The circuit has functions of judging the change of the data, locating and outputting strobe pulses. Usually, the output of each OR gate is 0 , and the strobe output is also 0 . If either terminal changes its stage, the corresponding OR gate will output 1 immediately, the jumping is fed back to the clock terminal of the 4 D triggers, and the general state is located. Then, all the 4 OR gates output low LEV. (View)
