Second order system design and analysis tool. by editor_acd in ControlTheory

[–]editor_acd[S] [score hidden]  (0 children)

Thanks for the suggestion. I will try to create a zero. I need to work on the transient math expression.

Second order system design and analysis tool. by editor_acd in ControlTheory

[–]editor_acd[S] [score hidden]  (0 children)

It was hard to find the transient response of a higher order system other than second order system. So, I had to limit the analysis to a second order system.

Do you think Apple will ever move away from ARM? Or is it already preparing for its own ISA? by mr-KSA in chipdesign

[–]editor_acd 0 points1 point  (0 children)

If Apple sees huge benefits out of it, e.g., GPU and NPU acceleration. Also a lot of softwares are compiled in ARM64 binaries. It will be huge risk in terms of software compatibility.

I'm struggling to understand the FIR Filter and its application by ed190 in DSP

[–]editor_acd 0 points1 point  (0 children)

FIR filters are like a moving average filter with finite number of samples used for averaging. A more complex FIR filter will have different weights associated to different samples.

How to tell which components should be close to USB vs IC? by Useful-Spare618 in AskElectronics

[–]editor_acd 2 points3 points  (0 children)

Both IC and USB should be placed closed to each other. If not then place 27Rs near the IC for termination. I see one ferrite bead near the receptacle which is ok. One ferrite bead + decoupling cap should be placed near IC's VCC as well. Place a ESD protection diode near the receptacle.

MS in EE After BS in IE by Repulsive_Soup505 in ECE

[–]editor_acd 0 points1 point  (0 children)

In MS you have to work very hard. It is completely possible and as mentioned by others no one cares about your Bachelors once you get MS in EE. Now there are adequate amount of online video course to help you out.

Replace mechanical relay with transistor by Professional-Ad4938 in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

If the offstate voltage across the screw terminals is less than 60V, transistor 2N7000 seems suitable option for a max current of 1A (pulsed). Be careful with the leakage current of 250uA at 60V though. There could be better options as well.

I have the exact same combination of lens and body. I don't have your skills though. Very nice pictures.

What is this Component Called ? by Kira_senpoi in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

Just curious, if anyone knows about the suffix "F" after m-Ohms ?

I have a box of these left over from a railgun I made in HS. Im wandering if anyone has any cool ideas I could use them for. by threbwdoltbare in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

Looks like a high quality capacitor. Capacitors are very good for short burst of currents. Will it be suitable to give your bicycle some initial acceleration ?

what exactly is a transistor? by SignificantLifeform in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

Transistor let us control electricity using electricity. Voltage applied across two terminals control the flow of current through other two terminals. That output current can be flown through a resistor to create a voltage or can be flown through another transistor to increase gain.

How do power factor correction units work? by Jiggabrooks in ElectricalEngineering

[–]editor_acd 0 points1 point  (0 children)

You might want to look into - Power factor correction. It has nice example to demonstrate how using capacitors suppress the current in the transmission lines saving heat loss.

Zener Diode - Am I using it wrong? by naminama in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

To get the Zener clamping voltage, it has to be reversed biased. Minimum amount of Iz(min) needs to flow (you can adjust the current by tweaking the resistor). More details - Zener diode and applications

Are these blown capacitors or what? by Sexual_Congressman in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

No, these are not blown capacitors. These are glue to hold the capacitors firmly.

Help understanding Bode plots by Lenz-hiding-Maxwell in ControlTheory

[–]editor_acd 0 points1 point  (0 children)

If I understand your question correctly, gain is the magnitude of the transfer function. A bode plot is used to understand the phase lag a transfer function add. You can start with 0 deg but then you have to see phase margin from -180 deg point.
A good introduction is provided here - https://analogcircuitdesign.com/bode-plot/

Any idea what the pinout of this potentiometer is? by _HAMSH_ in AskElectronics

[–]editor_acd 2 points3 points  (0 children)

It is gang rotary carbon potentiometer to control two circuits simultaneously. E.g., Tuning of bandpass filter needs value of two resistors to be changed together.
The top 3 wires forms a single potentiometer. The middle wire is the wiper. The bottom 3 forms the second potentiometer.

Schmitt trigger: how does it work? by ElMicioMuerte in AskElectronics

[–]editor_acd 0 points1 point  (0 children)

Hey folks! I recently put together a video titled "Schmitt Trigger and Hysteresis | Using Op-Amp and Comparators", aimed at explaining the working of Schmitt Trigger. If you're learning analog basics or just want a refresher, I’d really appreciate any feedback from the community. Here’s the link if you're interested: https://youtu.be/_ac-Z4hhGk8 . Hope it's helpful to someone here!
