Examples
Each frequency experiences a different phase shift as it propagates down the serpentine delay line, which forms different beams.
For example, the chrominance on odd lines would be switched directly through to the decoder and also be stored in the delay line.
The length of any digital delay line is a whole-number multiple of the sampling period.
This is normally done using a delay line like in SECAM (the result is called PAL D or PAL Delay-Line, sometimes interpreted as DeLuxe), but can be accomplished "visually" in cheap TV sets using PAL-S (PAL simple) decoders.
Very large serial-in serial-out shift registers (thousands of bits in size) were used in a similar manner to the earlier delay line memory in some devices built in the early 1970s.
