Ten Daily Electronic Common Sense-Section 64

Which power manager parameters are statically configurable?

• Power Manager enable/disable.
• Whether the application needs to call a specific user function when importing to reduce power consumption.
• Whether the application needs to reprogram the BIOS clock for frequency adjustment events.
• Whether the application needs to automatically make the clock domain idle when the CPU is idle.
• v/F adjustment enable/disable.
• CPU frequency value when importing.
• CPU voltage value when importing.
• Whether the application needs to wait when the voltage drops.
• Whether the application needs to make the clock domain idle when the DSP enters the deep sleep state.
• Which interrupts can make the DSP exit the deep sleep mode.

What are the advantages of integrating some or all of the analog power ICs with digital components such as baseband processors?

The advantages of integrating some or all of the analog power ICs with digital components, such as baseband processors, include significant savings in PCB space and overall cost savings.

What are the two tasks of the diagnostic interface J533 of the data bus?

One is to exchange data between the CAN drive system data bus and the comfort system data bus;
The second is to convert the diagnostic data of the CAN drive system data bus and the comfort system data bus to the K line.

3. Selective Signal Assignment
4. Process Statements
5. Block Statements
6. Components Instantiated Statements
7. Generate Statements

What is single photon detection?

Single-photon detection is a very weak light detection method. The photocurrent intensity of the light it detects is lower than the thermal noise level (10-14W) of the photodetector itself at room temperature. This signal drowned in noise is extracted. The single-photon counting method utilizes the natural discrete characteristics of the output electrical signal of the photon detector under weak light irradiation, and uses pulse discrimination technology and digital counting technology to identify and extract extremely weak signals.

What kinds of physical connections are provided by baseband data packets?

Baseband data packets provide two physical connections: connection-oriented 3 synchronous voice transmission channels (SCO) and connectionless 1 asynchronous data transmission channel (ACL), and multiple data transmissions can be performed on the same radio frequency.

What are the basic elements of the simplest electromagnetic interference model?

• There must be electromagnetic interference energy.
• There must be electromagnetic interference receptors. When the electromagnetic interference intensity exceeds the allowable limit, the interfered equipment will be confused.
• There must be a coupling channel between the interference source and the interference receiver to transmit harmful electromagnetic energy.

What are the main standards for microwave RFID?

ISO 10374, ISO 18000-4 (2.45GHz), ISO 18000-5 (5.8GHz), ANSI NCITS 256-1999.

What is the nature of fieldbus?

1. Field Communication Network
2. Field Device Interconnection
3. Interoperability
4. Decentralized Function Blocks
5. Communication Line Power
6. Open Interconnection Network
