To extend the measurement range of an available ADC(analog to digital conveter) we can use this autoranging. If it implemented on multiplexed input, this circuit will give best result. To adjust an ADC’s full-scale range we use a system autoranging that use LTC1257 because it is appropriate for system autoranging. During …
Read MoreFading a video signal can’t be done simply by attenuating the composite signal, since the synchronization signal may drop below unacceptable level. Here a circuit to overcome the problem: Most of video signals will works with this circuit, except for very noisy or distorted signals. The rest circuit is an LT1251 video fader …
Read MoreGamma correction need to be applied in video processing since the transfer function of video acquisition and video display is non linear. Here is the schematic diagram of a gamma circuit: If gamma value equal to 1, the the transfer function is linear. Typical CRT usually have gamma factor from about 2.0 to …
Read MoreCapacitance meter is one instrument that you should have in your toolbox if you are an electronics hobbyist, or if you’re a professional electronic technician. If you can’t afford to buy such instrument or you you can’t find it on your local store then here is the good news: you can build your own capacitance …
Read MoreHydrophone is a tool like microphone, but this tool is used in the underwater environment. When used to pick up a sound on the air then this tool becomes less sensitive because it’s mechanical-acoustical properties is designed to match the Acoustical impedance of water. Circuit shown in this article is the hydrophones …
Read MoreNeon lamp or tube lamp need high voltage to trigger the ionization of the gas inside the tube. After the ionization occurs, the voltage drops around 40 volts to maintain the current. To drive a neon lamp (fluorescent lamp) using 12 volts battery, we need to convert the DC voltage to high AC voltage. High …
