Abstract
In an apparatus having a CCD for compressing and/or expanding the time base of an input signal; a first two-phase transfer clock pulse signal made up of first and second pulse train signals having a first period and arranged to be 180.degree. out of phase with each other is used for driving the CCD while writing the input signal into the CCD, a second two-phase transfer clock pulse signal made up of third and fourth pulse train signals having a second period and arranged to be 180.degree. out of phase with each other is used for driving the CCD while reading from the CCD a signal which is produced from the input signal with its time base compressed or expanded, and the pulse width of the first pulse train signal is made virtually equal to the pulse width of the third pulse train signal and such pulse width is selected to be smaller than one-half of the smaller of the first and second periods.
