A ghost cancelling system eliminates a ghost by using a ghost cancelling signal formed from an input video signal including the ghost and adding the ghost cancelling signal to the input video signal. The divergence of the ghost cancelling circuit is avoided during the transient time of the channel selection or during the ghost cancelling process, and when there is the possibility that the ghost cancelling circuit diverges, the circuit is first made operable as a fed forward type circuit for a predetermined period and thereafter made operable as a feedback type circuit.
