A R-2R ladder circuit as the binary current divider that is finest application in digital to analog conversion. This video shows how to analyze the R-2R ladder circuit. In this video, the circuit has three nodes. First, this video shows analysis of the resistance on third node. Since the 2R is connected in parallel with 2R, they will give the […]
Read moreThis is a video about high speed analog to digital converter. Analog to digital converter (ADC) is a device that is used to convert an analog signal into digital. For example femtocharge, it implements the gain trough capacitor scaling, each pipeline stage has its input. Reducing the capacitance will increase the voltage. Here is the video : The femtocharge has […]
Read moreBelow is video tutorial about ADC architecture. This video discuss about the advantage and disadvantage of 3 ADC architecture. First is the approximation ADC. This ADC is widely used for medium resolution and medium speed. The second architecture is used for extremely high resolution . They are curerntly used in application like measurement, voice band, and radio. Finally, the third […]

Tremolo effect produce an amplitude modulated signal. Unlike vibrato effect that produce frequency modulated, this tremolo effect will produce the same effect as quickly turning up-ad-down your volume control repeatedly. Here is the schematic diagram of the circuit: Q1 is general small signal audio transistor, you can use almost any type of NPN small signal transistors. MFC3304P is a voltage […]

Below is a classic tone stack from the Big Muff distortion pedal. Basically, it’s a pair of filters whose output is combined through the 100k mix pot. The 39k/.01 filter attenuates the highs and only passes low frequency. But, the 3900pF/22k filter does the opposite. This filter passes the high frequency and filters out the lows. The 100k pot blends […]

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 […]
