More about precision (17)

28-05-2019 | Some people go to great lengths to generate numbers that are as random as possible. In issue 3 of 2017, we published a design for a Truly Ra...

4-05-2019 | This is a variant of the Random-Number Generator from Elektor 3/4-2017 and has a USB interface. Easy fine tuning of the analog filters.

1-06-2017 | From AC line-voltage and embedded power supplies to audio and serial data communication, differential voltage measurements deliver tangible...

6-05-2013 | Uses Zener diodes to generate avalanche noise signal, then differential amplifier (and a few analog filters) to eliminate deterministic effe...

6-05-2013 | Zener diode noise is processed, captured and recorded on an SD card. Passes all NIST tests for random signals.

1-07-1999 | Many applications require a precision voltage source which can be adjusted through zero to both positive and negative output voltage. An e...

1-07-1999 | The precision full-wave rectifier circuit shown in the diagram accepts a.c. inputs of up to ±3 V, yet operates from a single +5 V supply v...

1-02-1999 | The LM3812/LM3813 current gauges from National Semiconductor are suitable for application as battery charge/discharge gauge, motion co...
