ABSTRACT:
A pulse stretching circuit for a raster display for causing certain vertical control pulses to either have the same widths or at least terminate at the same time in both the odd and even fields. The vertical blanking pulses or vertical sync pulses in the odd fields are stretched so that they terminate coincident with the trailing edges of the 2H rate horizontal blanking or sync pulses respectively.
