The vegetables include potato, tomato, brinjal, pumpkin and fenugreek leaves: again, substitutions, such as squash for pumpkin, and sweet
Pulse-code modulation These rules may be violated to generate special symbols used for framing or other special purposes. The word "pulse" in the term "pulse-code modulation" refers to the "pulses" to be found in the transmission line. This perhaps is a natural consequence of this technique having evolved alongside two analog methods, pulse width modulation and pulse position modulation, in which the information to be encoded is represented by discrete signal pulses of varying width or position, respectively. In this respect, PCM bears little resemblance to these other forms of signal encoding, except that all can be used in time division multiplexing,
