Q. Parallel - flash converter?
Parallel / flash converter.
Also known as parallel A/D converter, this circuit is the simplest to understand. It's formed of a series of comparators, each one comparing input signal to a unique reference voltage. Comparator outputs connect to inputs of a priority encoder circuit that then produces a binary output. Following illustration demonstrates a 3-bit flash ADC circuit:
Fig: FLASH ADC Circuit
Vref is a stable reference voltage provided by a precision voltage regulator as part of converter circuit, not displayed in schematic. As analog input voltage exceeds reference voltage at each comparator, comparator outputs will sequentially saturate to a high state. Priority encoder generates a binary number based on highest-order active input, ignoring all other active inputs.
Octal to binary Conversion Conversion form octal to binary is the reverse of this process. Express each octal digit in three bit binary equivalent. Ex. Convert 3576
