a number of words that have an odd value outweigh the number of words they have

even value then for R [2: 0] it is R [2: 0] = max (A [2: 0], B [2: 0], C [2: 0] ] =

min (A [2: 0], B [2: 0], C [2: 0]). A circuit is required to be designed to perform the above

mode. Only comparators, multiplexers and gates of any crowd are available

inputs.

It is recommended that the total circuit be based on...

I need to read the signal of a second order low-pass filter to the serial plotter in the Arduino IDE.

The problem is a have concerns about how enter the signal; I just put the output of the circuit into the arduino and program the Arduino to read the signal?

I'll be greatful for any kind of help, thanks.]]>

I'm trying to design a PV emulator using a constant current source buck converter. It's a project given to me by my supervisor at uni. I've tried to use peak current mode and average current mode control systems but the way that works is that an outer voltage loop coordinates with an inner current loop but my supervisor wants both the loops to be current based.

I figured I could just place a sensing resistor after the load of the converter and place a sensor across it to get a...

current mode control buck converter with an outer current loop control]]>

Just started my coursework online and Im starting to get my head around the basic formulas but have had a brain malfunction.

Im trying to work out the formula for the following question.

The output of a series dc motor connected to a 210v supply running at 1230rev/min is 3.2kw

The supply current for this load is 20.5A

Calculate the Torque developed & Operating efficiency.

Torque = E Ia/ 2πn (but I need the Emf for this calculation?)

Emf = V - Ia (RaRf) (But I...

1)Two DACs are connected in the manner indicated in figure 1:

a)Deduce Vo based on Vb and B (t).

b)For what values of B is V0 defined?

2)Explain in detail the operation of a WATERFALL converter. Use a block diagram indicating how to carry out the conversion.

3)The digital conversion of a signal with the following characteristics is desired: Maximum...

my first question: i know that the mosfet Q1 is oscillated with a 10% duty cycle square wave with frequency around 60 hz from the 555, what is the output signal and frequency in L2, and how can i calculate it?

what is the role of C4 and C1 capacitors in the circuit?

and what is the role of D2 and...

Extremely fortunate I found this forum.

I am working on a project where I need to change the brightness of an LED on a breadboard by changes in the environment. It is sort of a bunch of little projects. One of which where I have a light sensor that depending on the light entering should brighten or dim the LED. The other is the same thing, but with a thermistor. The project consists of using a 9 V DC source, resistors, and wires.

I have been able to get my LED to turn off...

Question on inductors with initial current]]>

it's a simple inductor circuit.. first current passes through the circuit till it's charged fully storing energy inside its magnetic field.... However when the switch is opened later.. the reaction of the inductor doesn't make sense to me....

We know that inductors resist change in the current through them... before the switch was opened current was passing through the inductor entering from the upper...

FIrst of all I want to tel that my knowledge in this area is quite limited so please be gentle if I ask stupid questions

I work on a school project where I need to build a gauge with 4 load cells. I am using 4 x ina125P (one for each sensor) and read data using arduino and sent it to a database.

Now, this is what I have done :

1 - This is load cell (I have 4 of them) - load-cell.jpg

2 - this is how I am using ina 125 (I have 4 of this made on a test pcb) - ina.png

So each...
