Carry On Laughing which - by contrast - are broadcast regularly on British television. It is also considered much less successful at transferring the established formula to the small screen than the "Carry On Christmas specials". The series was conceived after the departures of two long-serving "Carry On" contributors: writer Talbot Rothwell and actor Charles Hawtrey. Furthermore, Kenneth Williams declined to appear in the series. Other "Carry On" regulars only appeared in a minority of episodes: Sid James in only the first four, Hattie Jacques in only one; and Bernard Bresslaw appeared only in the second series. In the absence of Rothwell, other
Starred transform starred transform is similar to the Z transform, with a simple change of variables, where the starred transform is explicitly declared in terms of the sampling period (T), while the Z transform is performed on a discrete signal and is independent of the sampling period. This makes the starred transform a de-normalized version of the one-sided Z-transform, as it restores the dependence on sampling parameter "T". Since , where: Then per the convolution theorem, the starred transform is equivalent to the complex convolution of and </math>}}, hence: This line integration is equivalent to integration in the positive sense along a
