Loving these lectures. Thank you for sharing.

Your lectures are very interesting and informative. I was disappointed you did not mention the measurement of very small resistances ( mili ohms ). I would have liked to have the explanation of the 4 terminal connection inputs, the theory and the accuracy of such digital instruments. I am designing and constructing this instrument at present. Keep up good work with further lectures, which I shall certainly follow.

Thank you so much for being very generous in sharing your lectures and expertise in your field of study.

Thanks for continuing this series. I've been really thinking of all electronic elements in terms of Thevenin Equivalents since your first episode.
It's been great.

Awesome information for this diy 25MWH off-grid HVAC GUY. Thank you.

Lots of industrial controls and monitoring instrumentation use a 4 to 20 mA signal for reporting back to a central control system.

[Shubhamyadav-zire]

hey sir, Your lectures are awesome!! Can you provide the PPTS of it..?

[gungagalunga]

B. Basic use in the school lab etc etc.

[gungagalunga]

would love to have the money to set up a lab

A 'function generator" shouldn't... IMO... be conflated with, or equated with, a "waveform generator" or "arbitrary waveform" generator. In the past, there were some very good, especially very good, analog based 'audio' frequency, "function generators.' The were expensive. The main purpose of these "function generators" was to generate periodic 'functions' of voltage versus time, in an accurate, and repeatable manner. Almost none of these instruments had more than a few functions: like sine, square, pulse, triangular, and sawtooth. Modern waveform generators, or arbitrary waveform generators, are almost exclusively digitally based. A modern digital "arbitrary waveform" generator relies on memory, data, a processor, and software to generate a wide variety of waveform patterns. Digital technology... used in modern "waveform generators" or "arbitrary waveform generators"... digital technology... allows for high precision, flexibility, and the facility to generate complex and custom waveforms, which is a great advantage over older, purely analog function generators.
