Electronic Design Workshop - Lecture 6

The transition from analog to digital multimeters represents a significant evolution in electronics, moving from scale-and-needle mechanisms to direct numerical representations. Analog multimeters were primarily built using galvanometers, which required complex switching circuits and were prone to parallax errors. To minimize these errors, analog meters often included a mirror on the scale to ensure the real needle overlapped its reflection. Before the digital and IoT era, long-term data recording was achieved through strip chart recorders—two-axis plotters where the x-axis was driven by an internal time base and the y-axis tracked parameters like voltage or temperature.
