Abstract
Simulated signal, produced by digital to analog converter, is important and necessary in many fields, such as electronic experiment, equipment debugging and maintenance, especially, in medical area. In this paper, the design and application of an effective software which may be used to generate simulated signal data by special wave picture obtained by scanner or drawing software are presented. First, we introduce how to realize producing needed data that meet the given conditions including amplitude, samples and resolution by this software. Second, the method and steps of getting the stimulated signal data from wave figure file is given. Third, an example of application about this software to generate simulated physiological signal data is shown. Then, the data are put into use and by digital to analog converter, an idea stimulated signal is produced. Therefore, with full confidence, we could draw a conclusion that it is very convenient and effective to get needed data for digital to analog conversion to generate all kinds simulated signal with a novel method.

Summary
In many fields, which include electronic experiment and testing, equipment debugging and maintenance, medical teaching, many special stimulated signals are often needed. As is known to all, all sorts of stimulated signals are often achieved by using digital-to-analog converter (DAC) which needs the corresponding signal digital data. For through the ADC, we must have corresponding original signal source as its input, while if not, we can get nothing about the digital data of stimulated signal. With this way, we must get original signal and face the problem—how and where to get it. We must get original signal and face the problem—how and where to get it As a result, it is not convenient and the resolution and samples of signals, which are limited by ADC, are fixed. We designed this software, which can be used conveniently and to generate automatically SSD with deferent samples, resolution and amplitude
