A balanced angle modulation detector having first and second angle modulation wave transmission circuits comprising; a differential limiter, balanced switching means, and a single tuned circuit for generating a quadrature signal wave such that a linear discriminator characteristic is obtained. One of the transmission circuits comprises a phase lag network including a resistor and inductor connected in series coupled to an inductor and capacitor connected in parallel. The quadrature signal wave voltage, developed across the tuned circuit, is coupled with the in-phase signal wave voltage to the input electrodes of a balanced switching device whereby the modulating signal information is recovered from the angle modulated wave.
