Hangzhou Dahua interview questions: 1. Explain the current sink and current pull. 2. English translation of a PCI interface. 3. Calculate the output frequency of the NOT gate crystal oscillator circuit. 4. A circuit crystal oscillator 22.1182MHz, serial communication baud rate is 9600, data bits are 8 bits, stop bits are 1 bit, use T1 mode, find the SMOD parameter setting value. 5. Design an asynchronous logic circuit. 6. A simple 51 single-chip microcomputer system peripheral circuit and the issues that need to be paid attention to. 7. Setting the output voltage of the PWM voltage-controlled oscillator circuit. Find the resistors R1 and R2. 8. Use the VHDL language to describe a hardware signal transmission interface through the CPLD chip. 9. A VDD outputs 10-40V. Since the output terminal is easy to contact the ground, design a power protection circuit. 10. The main technical indicators of audio amplifier chips such as LM833.
