I fully agree with OP considerations about measuring the transistor output curve. We can very easily and precisely set successive current values with constant increment. Thus, the IV curves will be...
Figuratively speaking, Olin Lathrop's answer is a wonderful story about the unequal "tug of war" between a "pulling up" resistor and "pulling down" switch. And, when the switch is 'off', the "strug...
The charger is supposed to output 20V-24V when the roomba is plugged in. However it's only showing 1.6V. If this is really true, then there is no point going further. The charger isn't working, t...
Setup We can best understand the behavior of the tunnel diode in the region with negative resistance if we imagine it as a self-variable (dynamic) resistor R driven by a variable voltage source V ...
Imagine a battery pack with <=60VDC of maximum voltage and a load of up to 10kW of power(the PMSM inverter with the input capacitance of up to 1mF). The load is not always known - could be 100uF...
Your question really comes down to how a delta-sigma A/D works. The A/D internally models the input voltage with a stream of bits. Each bit can only indicate the minimum or maximum voltage. The ...
A differential amplifier amplifies the difference between the two input voltages but suppresses any voltage common to the two inputs. Based on this scheme the differential amplifier is substrac...
Both differential amplifier and differentiator react to a voltage difference. But in the differential amplifier, the difference is between two voltages applied to the amp inputs at the same time wh...
I need to know what is the difference between differential amplifier and differentiator A differential amplifier amplifies the difference voltage between two signal voltages. A differentiator ...
A work around has been found for this and I'm sure this will get a proper fix before long: - Go to the edit button for your answer (for example) and press it Notice that there is no live preview s...
As an alternative to doing the math, as detailed in Andy's answer, you can use a graphical aid called a Smith chart: These were used routinely before computers to match transmitters to antennas. ...
$\color{purple}{\text{Are we there yet?}}$ No, it's not ready: - The embed image doesn't seem to work anymore on the EE part of the site and neither does it work here. It did yesterday because I a...
In my 15 yrs of intense deadline R&D for new state-of-the-art design in my 45yrs experience, estimation of time is inversely proportional to the number of mini failures from bad assumptions fro...
Although the voltage drop across the current-sensing resistor R6 is floating and it can "move" between the 28 V rails, the A1A op-amp input voltages can (have to) vary within the 5 V power supply. ...
Microwave Materials, Spectrum then EMI effects on SNR of WiFi, BT. There are a lot of measurable parameters in microwave dielectrics which affect; Dielectric Constant , Dk between conductors an...
Baud rate is about the speed of bit slots in the channel or symbols. Bit rate is the rate at which actual data is transmitted. Put another way, baud rate is what you see when you look at a scope ...
Our on-topic page currently lists homework questions as mostly off-topic, in the following manner: No interest in understanding or learning, "Just gimme da anser!" There has to be some element ...
Volt/Hz 176V / 60 ? Offtopic The motor appears to quite beefy from those specs, is it a traction motor? If it is a traction motor for a motor vehicle, driving it closed (FOC) loop will be nigh...
Actually I think this is a really good question. It's kind of more historical though I guess (and I don't know the historical answer either, but from building products perspective I think this is...
I used to live in the United States, and my microwave ovens' turntables turned at six rotations per minute (RPM). I now live in Israel, and my microwave oven's turntable rotates at five RPM. Annoye...
I have no record in electrical engineering; this is a total outsider question which might be grasped absurd. Wikipedia defines EMP as: An electromagnetic pulse (EMP), also sometimes called a tr...

Here is a video of the AN/PRM10, and here is a schematic (I believe the image can be zoomed): As most commercial grid dip meters produced in the past, this one possesses several functions in ad...
First, draw schematics properly when you ask others to look at them. Your right to left flow is rather annoying. There are two main possibilities for this circuit to cause noise, the inductor and ...
