4.2 Discontinuous disturbance
Switching operations in thermostatically controlled appliances, automatic programme controlled machines and other electrically controlled or operated appliances generate discontinuous disturbance. The subjective effect of discontinuous disturbance varies with
repetition rate and amplitude in audio and video presentation. Therefore distinction is made between various kinds of discontinuous disturbance.
The discontinuous disturbance is only measured with a measuring receiver including a quasipeak detector as mentioned in 5.1.1 and specified in Clause 4 of CISPR 16-1-1.
