| Abstract: | To overcome the defects of traditional signal generators such as less varied wave forms, big volume, high price, poor portability and so forth, this paper put for word a design of audio signal source based on MP3 player and digital voice recorder, it can realize the storage and management of multiple signals through line-in port and USB port recording. This paper mainly introduces the principles and schemes of the design, and list the test data and characters of the circuit related. |
