According to different situations, what kind of configuration can be divided into?
According to different situations, the configuration can be divided into three categories: default configuration, component configuration and structure configuration.
What is the difference between different Resistorss?
Ordinary resistors are the most commonly used resistors;
The resistance value of the precision resistor is more precise;
The fuse resistor has overcurrent protection function;
The resistance of the variable resistor can be changed within a certain range, and the resistance of the potentiometer can also be changed (similar to the variable resistor);
The resistance value of the sensitive resistor can also be changed under the influence of light or magnetism, and the resistance exclusion integrates a resistor network into one.
What is electrode life?
Electrode life: refers to the time that the electrode maintains the Nernst response, which mainly depends on the structure and properties of the membrane.
What is a photoelectric switch?
A photoelectric switch is a photosensitive element that receives the variable incident light and performs photoelectric conversion. At the same time, some form of amplification and control is applied to obtain the final control device that outputs “on” and “off” signals.
How does a WiFi device wirelessly access the Internet?
In fact, it is connected to the Internet through a wireless AP.
WiFi needs to be used in conjunction with wired broadband access technology (DSL, LAN, etc.).
After wired broadband access to the home, connect to an AP. Users can surf the Internet wirelessly at home as long as they install a wireless network card in one or more computers.
What is the difference between SOC design and traditional ASIC design?
The biggest difference between SoC design and traditional ASIC design lies in two aspects:
First, the co-design of software and hardware is being adopted more and more;
Second, the design of large-scale integrated circuits based on IP modules is the key to hardware implementation.
A complete SoC design should include architecture design, software design and hardware design.
What is the noise voltage?
In optoelectronic devices, in addition to the output signal voltage due to incident optical radiation. There are also random voltage values that fluctuate freely, called noise voltages.
What sequence of operations is the dialogue between the interface device of the IC card and the card?
- The interface device connects to the card and “active” the circuit.
- Cold reset of the card (Reset).
- The card’s response to reset.
- Information exchange is continuously performed between the card and the interface device.
- The interface device “deactivates” the circuit.
What are the characteristics of amorphous silicon TFT technology?
The driving method of a-Si T has the characteristics of simple process, low cost, and can be matched with the existing liquid crystal industrialization technology.
What is an intensity modulated fiber optic pressure sensor?
Most of the intensity-modulated fiber optic pressure sensors are based on the deformation of elastic elements under compression.
The pressure signal is converted into a displacement signal for detection, so it is often used in the optical fiber detection technology of displacement.
