The device below is built as an active stereo-tone/volume control for TV receivers, car radios and mains-fed equipment. The device below has function for bass and treble control, volume control with built-in contour (can be switched off) and balance. We can control all these function using dc voltages or by single linear potentiometers. This device has 4 features. The features […]
Read moreBelow is video tutorial about data converter basic. On this video explained about signal chain, where an input transform from analog signal into digital signal and then reverse it back, from digital to analog signal. This video also cover about integral non linearity, how they measure, and how to change it into differential non-linearly. Also covered on this video, the […]
Read moreBelow is video tutorial about fundamental of signal conditioning tutorial part II. On previous video has covered about amplification, instrumentation amplifiers and filtering. On this part II video tutorial will cover about attenuation, isolation, linearization, and circuit protection. Most data aqcuitition system input can measure voltages only within range 5-10 volt. Any voltages higher than this must be attenuated. To […]
Read moreBelow is video tutorial about fundamental of signal conditioning part I from measurement computing. On this part, there are three topics will be covered. There are amplification, instrumentation amplifiers and filtering. Simple data acquisition system contain a MUX, instrumentation amplifier and ADC. Mux or called Multiplexer acts as the input switching. This device will chose which input will be amplified. […]

In the circuit the rotary converter is nothing more than a second motor which is acting as a generator. The tools motor performed this function with the static converter, but at the cost of some loss of power. The idler motor is under no physical load but it cleans up the signal with the rotary converter. The only difference on […]

Capacitor have been use for decades to operate 3-phase motors on single-phase power. Two single-phase wires are connected to two of the inputs on a 3 phase motor on this method. Then, the capacitors is connected to one of the single -phase inputs and the third leg of the motor. Here is the schematic diagram of the circuit: The voltage […]

The diagram below shows us a simple block construction of an SCR (upper left) and its schematic diagram (upper right). The lower diagram shows us the operation of a PNPN device can best visualized as a specially coupled pair of transistor. When a proper gate signal is applied to the base of the NPN transistor, the connections between the two […]
