Abstract
A television camera comprising a television pick-up tube and an anti-microphonics circuit provided with a microphonics detection circuit (17) having a voltage-controlled oscillator included in a phase-locked loop circuit. The detection circuit (17) is not only used for switching on or off (15) the microphonics correction (14) but, as the circuit comprises a phase-locked loop resulting in a proper detection it is also possible to generate a test signal (24) by means of which the microphonics correction signal can be given the optimum phase via an automatic phase adjusting circuit (27). The microphonics correction circuit (14) comprises a low-pass filter (47-52) and a phase shifting network (53-60) for an independent adjustment of the amplitude and the phase.
