Corners and chambers that are a small fraction of a wavelength are not significant in the <4Ghz band. More significant is the tolerance and loss tangent on the substrate. They would hardly be m...
To answer some of your questions: Cable inductance: approx 1uH/m +/-50% depends slightly on l/d ratio , while cable impedance from sqrt(L/C) depends on twists/ft 50pF/m while coax is ~100pF/m ...
I never would recommend to use the "re model" for a BJT. The reason is as follows: The BJT is a voltage-controlled device (Ic is controlled by Vbe and the base current is an unwanted by-product...
There are a number of misconceptions here. bode plot db/Hz First, it's "dB", not "db". Second that's not a Bode plot. Those are dB/Log(Hz). In other words, a certain frequency ratio results in...
Your requirements are odd. Can you specify what purpose that filter is for? I'm saying this because, for a -0.1 dB/Hz, a filter will have a continuously increasing attenuation slope. Think of it li...
Signals with frequency above the cutoff frequency of a transmission line cannot be transmitted through the transmission line. But how can I calculate the cutoff frequency of a single phase transm...
In this case the antenna connector is the standard horrible little U.FL, which is connected with coaxial to a bigger one grounded to chassis. The main ESD risk is when someone is connecting or re...
Olin's response covered everything I would do in your situation as well. If the problem doesn't follow the probes and doesn't go away, I wonder if due to only two A to D inside the scope, this is t...
Your question doesn't make a lot of sense. for a sinusoidal input signal s = jω the pole exists at the resonant frequency ωr. Actually the pole exists regardless of what the input signal is. The...
I have decided to try design a band-pass filter with a cut-off frequency of 10kHz and bandwidth of 2 Hz. It's "10 kHz", not "10kHz". There needs to be a space between the number and the unit. ...
Reactance is the lossless part of impedance that stores and releases energy E=1/2 LI^2 or 1/2CV^2 . Much like a spring stores energy when compressed or expanded. L is a conductor that stores curr...
This is mostly another view on @Olin's answer. For different input signals the frequency of the pole will have different values ,the pole as a pole exists for some specific values of L,C s but t...
if we don't apply a sinusoidal signal at the input s may become a complex number $$$$ All real-world signals exist only on the $j\omega$ axis. Consider that a complicated signal can be broke...
This isn't a direct answer to your questions, but you should be aware of that to maintaining isolation means careful design off the PCB as well. You would do well to remember that if you are plann...
Is C2 here to protect the voltage source from thermal noise? There's absolutely no chance that any level of thermal noise produced by a resistor will be sufficient to cause any reasonably desi...
We use a DC externally excited generator/motor as a generator.We excite the input of the generator and get at the output 10V at 1Wb flux and at 5rps generator speed without connecting the generator...
I think the biggest reason is that it may be difficult to control your function generator with an output of only 5 mV. Some function generators have different output ranges that are switched, then...
Your generator constant is 2 V per Webber-Hz, or 2 V/(Wb Hz) = 2 (V s)/Wb. You somehow got a value of 5. The rest of your calculations are probably off due to that. Added I didn't have much tim...
It's pretty much just a direct substitute for the other 555 chip. Obviously you need to take care not to overload the other parts when you increase the supply voltage. The new part's 5Mhz max mea...
The problem was the transient you can see in the first picture, the blue one. When I connect the scope to it, it becomes stabilized. Otherwise it is noisy and because of this the other signal chang...
If you don't care about efficiency of the overall system, then a zener to limit the voltage will work. You are right in that a series resistor is not needed since the source is power-limited. One...
During the open circuit test of a induction motor ,not any current flows inside the rotor.But how can we achieve such a thing? Here is the ping configuration of a induction motor: The coils of ...
I suppose what you are asking is: "How to increase the strength of the magnetic field in a solenoid?" This can be done by increasing the number of turns of the solenoid as well as by increasing th...
It would help to provide links in your question to the datasheets. Without the datasheets I can only give general advice. Look a the memory datasheet and see what the setup and hold time requirem...
Possibly it is damaged. Be ESD aware and do not power up with any voltage on any pins > 0.5V (Latchup failure) If raising p9 (reset) does not lower Q to logic "0"=<20% Vdd) replace the ...
