What is Block Diagram – Everything You Need to Know
A flow block diagram is different from a general block diagram. It illustrates the functional flow of a system in a step-by-step process flow by adding elements and activities in a time-sequenced manner. This diagram is commonly used to represent complex systems. With a flow block diagram, the reader can easily understand the internal structure.

Microprocessor - 8257 DMA Controller - tutorialspoint
The following image shows the pin diagram of a 8257 DMA controller −. DRQ 0 −DRQ3. These are the four individual channel DMA request inputs, which are used by the peripheral devices for using DMA services. When the fixed priority mode is selected, then DRQ 0 has the highest priority and DRQ 3 has the lowest priority among them. DACK o −
Understanding Analog-to-Digital Converters: Deciphering
Nov 20, 2015Resolution and sampling rate are two important factors to consider when selecting an analog-to-digital converter (ADC). In order to understand these fully, concepts such as quantisation, and the Nyquist Criterion must be understood to a certain degree.
