本文介绍了一种遥测正弦校准信号发生器的新方案,关键是通过线路设计与参数选择,使发生器的3、5、11、13等谐波分量相抵消,使实际的最低谐波分量为7次谐波,给滤波器创造了较好的工作条件,从而最终得到良好的(失真度小于1％)正弦基波信号。 In this paper, a new scheme of telemetry sine calibration signal generator is introduced. The key point is to cancel out the 3rd, 5th, 11th and 13th harmonic components of the generator by the circuit design and parameter selection so that the actual lowest harmonic component is The seventh harmonic creates good operating conditions for the filter, resulting in a good (less than 1% distortion) sinusoidal fundamental signal.
