Microphone signals are AC voltages. Impedance is the “AC resistance” of audio signal voltages. Impedance controls the flow of the audio signal.In order for a mic signal to travel optimally, the microphone output impedance must “match” or “bridge” the input impedance (load impedance) of i...
What you see as a DC voltage or current is the result of a stable dynamic system, obtained through a proper balance of impedance modules, transfer blocks and feedback phenomena, even in the simplest circuits with no apparent reactive component.Furthermore, one can say "high impedance" or "lo...
aImpedance (Ohms) represents the total resistance that the cable presents to the 最重要的特征在一电子缆绳是阻抗,衰减,保护和电容。 在这页,我们可以非常一般只回顾这些特征,然而,我们将较详细地谈论电容。[translate] a请输入您需要翻译的文本!下午好,首先很感谢您能给我这么一个机会, Please input the tex...
Conclusion Transmission line pulse testing is an important analysis tool when designing and evaluating system ESD protection. While it doesn’t perfectly correlate to industry ESD standards, it provides a very close first approximation by allowing comparison of internal IC protection structures to external...
A SerDes implementation includes parallel-to-serial (serial-to-parallel) data conversion, impedance matching circuitry, and clock data recovery functionality. The primary role of SerDes is to minimize the number of I/O interconnects. Click to see the detail Why Do We Need SerDes? Distributed...

Significant consideration is placed on maintaining the harvest as potato storages are being loaded. One major concern is loss of water from the tubers throughout the storage season.It is a common practice to wet the floor in the storage prior to harvest. It is also recommended to maintain hu...
When working with high-speed or high-frequency channels, we generally use S-parameter measurements as important signal integrity metrics. These are defined in terms of some reference impedance, which is normally taken as one of the above values (50 or 75 Ohms) since you might be interfacing wi...
Why is impedance not a phasor? Why does increasing pH melt helix? Why do surface currents move a lot of heat? Why is there an enhanced Fujita scale? Why is gravity a weak force? Why does blood pressure drop so low in the capillaries? Why does the weak force violate parity? Why do ...
Why is impedance not a phasor? Why does a voltmeter have high resistance? Why does a circuit need capacitors? What is their purpose? When are series circuits useful? How do parallel branches work in circuit analysis? How does increasing the resistance in a circuit affect the current in the ...
