    Help how to build a dc voltage interrupter to control power on and off time. PWN not sutable.

    If you use a Nano or Uno board timing is very accurate, as they both have xtal oscillator on them. Easy way is use mBlock to do the code. Here I have 3 inputs each with a button, a pullup, and one output to drive NPN or MOSFET to control heater power. mBlock takes block configuration and...

    Two-Pole Passive RL Low Pass filter

    You dont "HAVE TO" have Q in your equations, its just another look at a networks behaviour. That being said a 2 pole filter can exhibit "peaking" which is where Q is often used as an indicator or the level of peaking. Example in a LPF ...

    Simplify first : 1) R5 and R6 are in series, so what would the equivalent R in place of them be ? 2) The equivalent R from 2) is in parallel with R4, so whats that new equivalent ? 3) You now have a simple V divider to compute V4...... Regards, Dana.

    Maybe I am missing something but I thought he had equal L and R values ? Regards, Dana.

    Two-Pole Passive RL Low Pass filter

    This is what I get for T(s) Isn't the problem with your That's the G due to two identical single pole cascaded stages, but your circuit is not two identical cascaded, there is no buffer of G = 1 between the two stages. The second stage loads the first stage, so they are not "true"...

    Just get a cheap inverter, DC > AC, from a auto parts store and use a car battery to power the inverter. Regards, Dana.

    Spectrum analyser Equalizer project how to go about it?

    I just got notified Freesoc2 board still available, it has the I/O also you may need. check it against the 050 board. Note its an obsolete board, but not the PSOC on it. I believe you can still get the gerbers for this board on GitHub, in case you needed more at a later time, check this out...

    https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIA4GcD2BjEBdAvkA Just a thought but I am thinking you need to hire a consultant to proceed with complete product definition, goals, choices. There are partners, you will have to search on it at Infineon, that are...

    Use Digikey and look at PSOC 5LP family chip pricing.

    I use Simetrix spice simulator. Was Analog Devices main sim until they bought Linear tech and sadly settled on LTC Spice.

    Spectrum analyser Equalizer project how to go about it?

    Thats were the code and sampling come in. 1)So you create an array whose size is replication of your desired frequency resolution, and then write a routine to start an A/D and fill that array. 2) Once filled you run the FFT code on that which creates an array where each ROW is the frequency and...

    The forum encourages users after they have made basic attempts at doing thins. So I am going to decline to make your drawings. So take small bites,. use an online tool for drawing schematics, tackle a drawing for 1 column, and ask for comment. Regards, Dana

    I think before you go any further you need to work with basic board, part, and IDE, to start getting a feel. Just a thought. So try a reduced solution first to see what you can accomplish and then migrate to the bigger board. Regards, Dana.

    Spectrum analyser Equalizer project how to go about it?

    You keep changing the specs of x and y of the display ? So now you want 50 frequencies and 10 segments / frequency, so you need for the matrix 10 rows x 50 freqs or 60 pins. That board has a lot more pinout than the 059 board....its manual : The board pins available are sections 4.2.6 The...

    Spectrum analyser Equalizer project how to go about it?

    Filter case : It can be overlapping or non overlapping, depends how you configure it. The examples I showed are very narrow band, high Q filter solution, so effectively non overlapping. A FFT has a problem in that at each freq bin that it generates its very narrow band, very precise. Sp when...
