.. and output was also required, so I could not use an integrator or other simple design. The circuit is used in a distance meter, which is why little and constant delay between input and output pulses is so important. Testing has ...
.. simple equations (R S is the series resistance, L and C the reactive elements and F R their resonance frequency): This Q-meter is unusual on more than one count: it is capable of displaying directly the value of the series resistance, and ...
.. Design Idea presents a very accurate, yet very inexpensive, capacitance meter. It was specifically designed for measurements of low value capacitance with an accuracy of better than 1 pF ...
.. most realize. Take, for example, the smart grid with smart meters. Every day utilities are installing a shiny new smart meter on our house and encouraging us to take control of our energy future. We are to monitor and report consumption ...
.. Experiments were performed with a single solar cell of diameter D=7.5 cm positioned horizontally on a desk located 1 meter from a window. Although it was sunny outside, practically no direct sunlight passed through the window. Under ...
.. when using the SPIRIT1 with a range extender under EN 300 220-1 (v2.3.1, 2012-02) in the 169.400 - 169.475 MHz band, meter reading, tracking and tracing applications. The maximum allowed output power in this sub-band is +27 dBm (500 ...
.. will produce usable results at a low cost. Figure 1. If the simplest version is required, use an inexpensive volume-unit meter to replace the 0- to 100-uA meter. Three LEDs are used; experimentation will indicate which device has the ...
.. switch. At the start of the on time, S 2 and S 3 are closed, biasing Q 1 on from the 5.5V power rail, and the diode and meter disconnect through S 1 and S 4 . After the current in the inductor under test, L X , has exponentially reached ...
