Abstract

In this parallel-to-serial converter, parallel analog signals are converted to a series of amplitude-modulated pulses. The converter is used in a transmission system to serialize the parallel outputs of a linear array of photocells.

Analog Parallel To Serial Converter

In this parallel-to-serial converter, parallel analog signals are converted to a series of amplitude-modulated pulses. The converter is used in a transmission system to serialize the parallel outputs of a linear array of photocells.

Specifically, the analog output from photocell 10 is amplified by transistor 11 and applied to coil 12 on a transfluxor 13, thus setting the transfluxor to the analog flux level. Transfluxor s 13 are interconnected by a drive line 14 having delay circuitry 15 between each transfluxor, with the transfluxor itself providing a portion of the inductance of the delay circuitry.

Upon receipt of a drive pulse at coil 16, each transfluxor delivers an output pulse on coil 17 proportional in amplitude to the illumination on the photocell which it samples. After the drive pulse propagates to the end of drive line 14, a reset pulse is applied on line 18 to reset all of the transfluxors.
