【Abstract】 A intelligent capacitance-coupling testing system is introduced in this paper. It tests mutual capacitance, capacitance unbalance - pair - to- Ground and capacitance- coupling automatically. The core of this system is MCU. The option menu and the testing results are displayed on a LCD; the testing results can be saved in FLASH and printed out, or sent to a PC by RS- 232. At the last part of the paper, it introduces the digital realization of the circuit.更多还原
