Analog to Digital Converter (ADC) - Block Diagram, Factors The analog signal is first applied to the ‘sample‘ block where it is sampled at a specific sampling frequency sample amplitude value is maintained and held in the ‘ hold‘ block. It is an analog value. The hold sample is quantized into discrete value by the ‘quantize‘ block last, the ‘encoder‘ converts the discrete amplitude into a binary number. MUX - Digital Multiplexer | Types, Construction & Applications Each input line is known as a channel.A MUX can have 2 n channels depending on the number of control signal “n” A MUX having Analog channel is known as analog MUX, which is used for Analog inputs. Multiplexers are essential in communication equipment for placing many signals onto a single channel using Time Division Multiplexing (TDM) to reduce the number of the channel used per user. Build Your Own ELECTRIC MOTORCYCLE : 16 Steps (with Wiring up the controller power cables to the motor and batteries is fairly straight forward. The motor controller comes with a manual that includes the wiring diagram. The Alltrax Document Depot is a great resource for all sorts of information on controllers, batteries, and motors.
