Conclusions
It has been shown that when the excitation coil of an electrodynamic instrument is fed with a current (voltage) having sinusoidal balanced amplitude modulation, the constant term of the pointer deflection is produced by the control-coil nonsinusoidal amplitude-modulated current (voltage) which is in synchronism and phase with the excitation current (voltage) carrier and envelope.
Such a detector can be used for measuring the vectors of amplitude-modulated currents (voltages).
