To properly answer this question, you need to show us a real circuit with a capacitor across the supply. There are various reasons a capacitor across a power supply might make sense. Protecting t...
You still haven't said why you need, or even what order, type, etc. Assuming it's a 2nd order, an exact solution involves creating a generic transfer function and then solving a system of equations...
It seems you have ground loops, and possibly having multiple ground connections shorting out your signals. Your hand-sketched diagram is a good start, but you need to show all the ground connectio...
I was the one who started that list Elsewhere. I thought the same as you, that a few common abbreviations would be good to have in a single place. However, it quickly turned into a mess. After o...
The oversampling is said to simplify the LPF yet the better reason is that it improves the SNR. Lower noise comes from better image rejection, lower filter ringing, and significantly lower group d...
Does your produced CPL file correspond to the Altium layout, or to what Eurocircuits Assembly Visualizer is showing? Open the CPL file in Excel and check. If the Altium output is wrong, I'd say ch...
I support this idea and think that it might fit the Papers category, although it should be allowed to have multiple users maintain and moderate it. It should be a brief glossary for a quick look-up...
You are asking how to analyze this circuit: Forget about what you think it should be called. Before attempting to model specific aspects, first try to understand the circuit. The opamp provide...
A resistor is not a good model for a saturated BJT. According to your graphs it is, but those are simplified. There isn't really a single slope for all base currents as your graph shows. Even if...
I want to find the conditions of oscillation of the following Hartley oscillator.I have attached a load (ZL) to my Hartley oscillator I have written KCL for nodes A,B: For node A: $$\frac{V_{A...
MissMulan - at first, you should show which nodes are connected (crossing points). Secondly, where are the voltages Vo and Vin in your diagram? Please keep in mind, that it is essential to OPEN t...
Filter design 101 given hypothetical high-pass (HPF) filter -3dB gain HPF at fc attenuation of -8dB at fc/2 Assumptions gain = 0 dB at f>> fc Ripple between -3dB and 0 dB...
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...
There are plenty of ways a single diode and a couple of resistors can perform multiplication (RF mixing). Consider this circuit that takes two inputs (a 1 MHz sinusoidal carrier wave and a 10 kHz t...
