The frequency point at which the capacitive reactance and resistance are equal is known as the cutoff frequency of a low-pass filter. At cutoff frequency, the output signal is attenuated to 70.7% of the input signal value or -3dB of the input. Consider a first-order low pass filter with ...
The spatial distribution of impedance in your ground plane is also important, particularly in mixed-signal devices. Signals will follow the path of least reactance back to the ground return when traveling in the ground plane. Ideally, the path of least reactance in a star, point-to-poi...
In an AC (alternating current) circuit, the calculation becomes slightly more complex due to factors such as power factor and reactance. For these systems, it's crucial to understand how to handle these variables and the impact they have on the calculation when trying to figure out how many ...

the MAX30009 uses an I/Q demodulator to split the received analog signal in its I/Q components (in-phase and quadrature-phase with the stimulus signal) offering resistance and reactance measurements capability with an 0.1% accuracy. The two resulting signals are then fed into a programmable gain...
However, as the measured signal’s frequency increases, the capacitive reactance decreases. At higher frequencies, the probe’s impedance decreases causing much greater probe loading. The larger the probe’s input capacitance, the more it’s going to disturb or load the circuit when the measured ...

But in fact, this method is not easy to do, because we need to find a high-quality magnetic ring with high inductance (high permeability), so that it can completely eliminate the error in the very low measurement frequency range. In addition, it is sometimes difficult to judge whether the...
Usually the best thing to do is to find an AC flyback transformer and swap its core for something heftier. Special attention must paid to prevent saturation that could otherwise occur at 15 volts per turn; pick a core with a low permeability, a large cross sectional area, a small ...
Low impedance is important to speaker cable Impedance is dominated by resistance at low frequencies Impedance is dominated by inductance at higher frequencies Capacitive reactance is insignificant compared overall circuit impedance and will only affect signals that are well over the +100 kHz range The ...
