*PCM*

(“pulse code modulation”)

.

*[transfer] a [narrow-band analog signal] over an [analog base-band channel] as a [2-level signal] by ‘modulating’ a [pulse wave]*

.

(some ‘pulse modulation schemes’ also allow the narrowband analog signal to be transferred as a digital signal (i.e., as a quantized discrete-time signal) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example, some line code)

.

(these are not ‘modulation schemes’ in the conventional sense since they are not channel coding schemes, but should be considered as source coding schemes, and in some cases ‘analog-to-digital conversion techniques’)
