I use to sell sound analizing equipments year ago. From what I remember, you would need an audio range spectrum analyser to gather the raw data. Then with the specturm data you could create your own computer analysis with a simple microcontroler such as arduino. The tricky part of your project...
Attached is a PDF. It show my modified version of your amplifier with the LT1166 implementation.
DIDnt try it but pretty confident that it should work as expected since your version was said to be validated with the simulator.
Hope you will try that and let us know how it goes.
Sorry for the delay to get back. I have taken a look at this document from Cordell:
https://www.cordellaudio.com/papers/MOSFET_Power_Amp.pdf
Look at figures 7 and 12. In both examples the drivers (ie: your Q10 Q44) are connected with an Emitter resistor. Furthermore instead of using a PNP to...
Here is a Poor Man Charging solution. Not that I think you may be a poor man, but hey, anyone can use a little inexpensive trick once in a while :)
Your power adaptor is adequate for changing your battery providing that you impose a current limitation strategy to be on the safe side.
Just...
According to R12,R13,R22,R23 and theoretical bias voltage for M1,M2,M3,M4 you should read approx. 8Vdc between opposed MOSFET gates. That is theoretical. In practice, although I have not reversed engineered that schematic completely, it appear at first glance that this circuit would be quite...
Here is another hint. When your sensor output -5V your ADC should read Zero. Since you have R2(pin1) at +5Vdc and and R2(pin2) at Zero when the ADC read Zero, this imply that you have the same voltage drop between R2 and (R1+470), so, this tells you right away that R1 = R2-470. Now you can find...
With OrCAD Allegro and a *.dra footprint file I am trying to build myself a document listing all images and footprint data.
When I load a footprint .dra file into Allegro I can see the footprint image and obviously Allegro knows what are the dimensions of that footprint since it can build a PCB...
Does anyone happen to know what the acronym SPB stands for in Cadence Orcad Allegro SPB 16.5
I know it is a software, I use OrCAD 16.6 myself, but i am curious where is the SPB comes from ?
Some ideas I search for (unsuccessfully) : Soft Printed Board - Sub Printed Board - Super Power...
Your proposed schematic show a 0.1 ohm resistor. Assuming this is the shunt you want to use I think you have a major discrepancy here. 3mV/ma = 3V/A = 3 ohms. You are far from 0.1ohm. If you put 500mA into a 0.1ohm resistor you will end-up with only 0.05Volt. That is 50mV, not a lot for...
You say yo disconnected one channel at the input and the Hum dissipated ?
This means you have a bad channel with a hum or a very poor quality audio source that is incapable of supplying some 500ish micro-amps. try inserting a capacitor at each separate input, like a 10uF each. This will prevent...
Practically speaking, I agree 100% with you. The quickest solution is to modify the Capture Symbol. This is what I will end-up doing anyway. But on a more educational point of view, I cannot believe that such a basic situation has not been taken into consideration by OrCAD programmers. Yes, the...
Re: Is "Direct drive LED" more efficient than using a switch mode LED driver?
To be honest with your I cannot quote any research on that question. I would have to guess an answer on that.
First, when I mentioned that SMPS can achieve 95% efficiency I was referring to a best world situation. For...
The average voltage of a sine wave is given by the formula:
Vavg = Vpk * 2/pi (where is pi, is it π ? ) ok then 2/π
see: http: V average Formula
Because the input voltage = 10 Vpp AC the corresponding Vavg would be 6.36V
Because you chop that signal half of the time the Vavg would be ÷2...
First of all, Out Of Circuit capacitor is supposed to be Open and coil is supposed to be Close. A coil is a usually a piece of copper wire wrapped around, hence, should read CLose. Capacitors, when under test will take the charge from your tester and eventually become full at the same potential...
My answer is not one based on electronic specifications and engineering point of view but rather simple common sense, and it goes like this. I would never buy Any product from a company for which I cannot reach and have the address in case I need support from their customer service, at any cost...
