Common analog electronic circuit
An amplifier circuit, a filter circuit, an arithmetic circuit, signal conversion circuit, the signal generating circuit, the DC power supply
Electronic system design principles:
1, the circuit as simple as possible, it can be integrated with the integrated
2, consider the electromagnetic compatibility
3, the system sets a test point, the self-test circuit
4, choose a device, can be cheaper on the cheap
5, and board production welding, assembly process considerations
