I'm thinking out loud here and haven't solved this yet. This answer is logging my process as I try to solve the problem. It may very well result in the same long-winded process you went thru. No...
If we have the transfer function of a LC high pass filter: $H(s) = \frac{sL}{sL+\frac{1}{sC}}$ If we want to find the pole of that filter in the end we get: $s = \frac{j}{\sqrt{LC}}$ and for a ...
I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue. How do I find the voltage gain? When no feedback is there, we just find the output resistance and the current...
Easy way to convert over long comment into an answer. It would be great if while typing a quick comment to a question you realise that you are about to exceed the character count and it is a valid...
you want a current source start with a linear regulkator like LM340 and use the relays to switch in different load resistors.
CATV distribution is typically half-inch rigid coax, so it's not that. It looks more like a fibre junction box "aerial fibre terminal" in the parlance.
Load line Formal "explanation" In common emitter collector we just draw a line from the vertical axis (Ic) at the point (0,VCC/RC) to the horizontal axis at the point(VCC,0) and where that line...
I have a hat board that has some high power solid state switches (mosfets). The hat is controlled by the main board. The hat and the main board are connected via pin headers, like an arduino. Th...
Some optos are really slow. What off time is yours specified for? Your circuit could be better. The transistor is turned on thru 1 kΩ, but off thru 11 kΩ. You are also giving it way more base c...
I changed value of resistor R318 from 10 kΩ to 1 kΩ, and that alone significantly improved off-time. From 200 μs to around 25 μs. That is much better. So I looked into datasheet again. I found t...
I was experimenting with a transimpedance amplifier and a photodiode, the circuit was the following: Input current was initially calculated to be 500nA, which would produce -2V output. Current s...
Your current FIFO acts as a standard FIFO. What you desire is a First Word Fall Through (FWFT) FIFO or a showahead FIFO. Changing the rd_data to be combinational logic instead of registered logic i...
I would suggest finding the root cause of all the noise and eliminate as much of it at the source. Baluns, active guarding, double shielding, buffering, current source control and matched impedanc...
This looks like the block diagram was done by a technical writer, not the designer. It is someone's conceptual misunderstanding of a linear servo with feedback relays and optional FET drivers with...
This problem investigates the behavior of the voltage across the capacitor in response to a step input: - I am asked to find the voltage Vc(t) without the use of differential equations or simula...
Fault Codes (Page 38) PE ground is mandatory to be functional and is tested. Typical standards expect < 25 Ohms for residential zones. RCD's and similar testers use as test resistor to forc...
The voltages from the raw microphone are quite small and fairly high impedance. That's why an amplifier at the mic is needed in the first place. The signal on the wire would be way too small comp...
Hi All, I have a query regarding the cable sizing and motor starting. I have a 200HP motor to feed Low voltage power @480V. The distance between the substation and the motor is 2000m. Voltage dro...
I don't find any of such cables, and the discussions on the web revolve around SATA being point-to-point and not designed for networked or shared storage. However, if one'd build a cable that is j...
without the use of differential equations or simulation Then use Laplace transforms to derive the transfer function. Multiply it by 1/s to get the Laplace result when a step is applied then, u...
Why can the channel capacity C of the additive white gaussion noise (AWGN) channel be denoted in different ways and how do they relate to each other? Examples: C = (1/2) * log2(1 + SNR) [bit?] ...
The other answers are excellent justification to the the industry standards imposed on CMOS logic. The historical migration to smaller lithography CMOS led to lower Cds values which led to faster ...
Adding to what Lundin said (+1): s is seconds, S is siemens (1/Ω). What we write here is inherently HTML. Greek characters like µ and Ω are defined as HTML entities, and can always be writte...
The spec 79V 0.5 ohm 5ms = 62.41 Joules . The TVS must be rated for a low temp. rise at this energy dump or higher. MOV's are limited by the number of discharges as the oxide wears out, but may be...
I've noticed there are a lot of tags referring to general physical quantities (e.g. current, voltage, frequency) I'm not sure if they are useful. For example, what usage would have the tag voltage...
