Electronics Workshop - February 28, 2019

Time & Location:

Topics:
  1. An Arduino Simulator
  2. A Digital VOM Interface to Pro-2004 to Measure Deviation
  3. Contact Bounce

Notes:
  1. Analog Devices AD736 (positive output) and AD737 (negative output) are true RMS-to-DC converter ICs.
  2. Everyday Practical Electronics' "Electronics Teach-In 9" has a wideband AC range extender circuit using a "precision" rectifier to convert a 20 mV or higher AC signal to a DC voltage representing the RMS value of the input.
