I wish to know what is the intuitive meaning of Cauchy's integral formula... What does it try to do...!!! I've searched quite a few places on net but those descriptions are pretty much mathematical...!!! They all talk about a disc and winding numbers and rotations etc... In bits and pieces, I...
Dear Experts:
I am trying to copy and make a LVDT excitation Circuit from the following link:
https://www.mikesflightdeck.com/lvdts/lvdts.html
I need help in understanding and troubleshooting the last circuit schematic (Signal Source) in the above link...!!
The stated aim of the circuit is to...
Thanks for the replies... I think that WAS indeed the problem... I had powered up OP07 with +5 VDC and Ground...!!
I would also like to know if I should be worried about the choice of Resistors in Differential Amplifier given the fact that the resistance between Output + & Output - is 1...
Hello I've uploaded a circuit and I request some help on this circuit...
The sensor part: The Sensor part requires +5V DC between Input + & Input - Terminals... So I fed it with a SMPS... +ve of SMPS goes to Input + and Ground of SMPS goes to Input -....
Under no load conditions voltage...
My LM2907-8 Pin Ckt is still not working.... :(... I am trying to test a freq to voltage converter.... I was trying to implement Figure 6 of the Application Example in the following datasheet of Texas Instruments...
https://www.ti.com/lit/ds/symlink/lm2907-n.pdf
The output is held at 0 for any...
Hi, I was trying to work with a standard circuit based on LM2907 for freq to Voltage conversion... The ckt is available in its datasheet, in Typical Applications (Minimum Component Tachometer) [https://www.emesystems.com/pdfs/parts/LM2907.pdf]... I am trying to replicate the ckt on a...
Thanks... That was helpful... Will try to 'copy' some circuit based on f/v converter.... I checked out the application notes of the IC itself and it had some circuits there... Thanks again..!!
Hello,
I dont wish to use a Microcontroller... (Cos I donno abt it.. :).. ) I just wish to keep it simple but fairly accurate... Following is what I am looking for:
Pulses of varying width will be generated from an optocoupler connected to a Wind Speed Sensor... These pulses needs to be...
Friends, I need to make a Stable AC current source.... It should be able to vary the current using a Potentiometer from 1A to 5A of about 100VA rating....
Wouldnt C3 in the circuit take care of the high freq noise associated with 3V3?? Why are, then, so many other capacitors needed for each pin of the IC to the right....
Thanks js - for a possible solution.... I guess, this will need a microcontroller interface too.... Currently, I dont have any set-up to interface a microcontroller with such a device.... I was looking for a pure hardware solution.... But still, I'll try this one if nothing else works out...
The relays are going to be operated occassionally - once in a month or even less....!!! So detection time is not a limiting factor...

I mean the relay will remain in one state for an extended period of time...
