THE DESIGN OF VERY LOW FREQUENCY ELECTRO-MECHANICAL SIGNAL GENERATOR
Jiabin Shen · Acta Automatica Sinica · 1965
In this paper a very low frequency electro-mechanical signal generator driven bysynchronous motor with extremely low frequency and amplitude drifts and constant out-put impedance through the entire operating range is described. It is suitable for testing and analysing electronic recorders and other control devices.
