1.Explain the operation of an encoder. (1 point) _It is a device that converts a weighted numeric input line to an equivalent digital code. 2.What does it mean when an encoder is a priority encoder? (1 point) _Logic establishes a rank order for inputs and always accepts the higher of multiple inputs. 3.Describe one practical application that uses encoder. (1 point) _A TV remote control or a 10key keypad. 4.Explain the operation of a decoder. (1 point) _It is a device that converts a digital code into a single output representing its numeric value. 5.Describe one practical application that uses a decoder. (1 point) _It is used in computers to handle operations with memory, or used to drive 7 segment displays, or used in applications that require the outputs to be in decimal form, such as calculators. 6.Search through datasheets for the 74148 device to find an application note that shows how to cascade two 74148 encoders to create one 16-to-4 line priority encoder. Draw the schematic for the 16-to-4 line priority encoder. (8 points)
