New 1,4“ round display module from company 4D Systems with a round pixel placing is able to truly display various analog variables. The evolution sometimes shows, that not everything “new” is automatically better than something „well-proven“. One of examples was also a „boom“ of digital panel meters, when it seemed for a while, that the

In this episode Shahriar explores the world of Delta-Sigma modulators with emphasis on a Delta-Sigma Analog to Digital Converter (ADC). The basic concepts of analog to digital conversion is presented, particularly with respect to quantization noise spectral shape and power density. Next, oversampling ADCs are presented to demonstrate the possibility of increasing SQNR (ENOB) through

Some notes: 1. The C3 can be omitted, its purpose was to filter noises picked up by connecting cable between board and sensing transistor, but as the transistor is mounted on the board it become unnecessary. 2. R8 is optional and is for reducing the fan speed. Its value must be calculated according the fan
