Apparatus for compressing and/or expanding time base
An apparatus for compressing and/or expanding time base using a CCD (22) adapted such that an input signal supplied to the CCD (22) is obtained as a signal with its time base compressed or expanded on the output side of the CCD (22), a first two-phase transfer clock pulse signal made up of first and...

| description | An apparatus for compressing and/or expanding time base using a CCD (22) adapted such that an input signal supplied to the CCD (22) is obtained as a signal with its time base compressed or expanded on the output side of the CCD (22), a first two-phase transfer clock pulse signal made up of first and second pulse train signals (P'o1, P'o2) having a first period and arranged to be 180 DEG out of phase with each other is used for driving the CCD thereby to write the input signal to the CCD and a second two-phase transfer clock pulse signal made up of third and fourth pulse train signals (Q'o1, Q'o2) having a second period and arranged to be 180 DEG out of phase with each other is used for driving the CCD thereby to read from the CCD a signal which is produced from the input signal with its time base compressed or expanded, in which the pulse width of the first pulse train signal (P'o1) is made virtually equal to the pulse width of the third pulse train signal (Q'o1) and the pulse width is selected to be smaller than a half of the smaller one of the first period and the second period. |
