正弦信号发生器是一种常用的信号源,在科研、教学、生产、生物医学、测量等诸多领域得到广泛应用。早期的正弦信号发生器大都采用频域合成法,即将一个高稳定度和高精度的标准频率正弦信号经过加、减、乘、除四则运算产生具有同样稳定度和精确度的大量离散频率的正弦信号,但这种 Sinusoidal signal generator is a commonly used signal source, widely used in many fields such as scientific research, teaching, production, biomedicine, measurement and so on. Most of the early sinusoidal signal generator using frequency synthesis method, a high stability and precision of the standard frequency sine signal after addition, subtraction, multiplication, addition to four operations have the same stability and accuracy of a large number of discrete frequency sine Signal, but this
