Why is priority encoder used instead of the regular (standard) encoder?

How are bias errors different from random errors?

How do you design to 2-4 active low decoder?

Consider error control methods in digital signal transmission. Assume Hamming code is used with even parity. (a) Assume the received code word is 1110101001, determine if the code word is correct. If no, identify the wrong bit and obtain the original data word. (b) If the analogue signal before digitalisation is of frequency from 200 Hz to 1.5k Hz. What is the lowest sampling frequency? (c) Following (a) (b), determine the bandwidth requirement for transmitting the digital message.

Questions 1. What is the difference between accuracy and precision? 2. List four sources of poss.ble errors in instruments. 3. What are the three general classes of errors ? 4. Define (a) instrumental error, (b) limiting error, (c) calibration error, (d) environmental error, (e) random error, (f) probable error.

Write down a Verilog module implementation of a 2-to-4 decoder (and/or encoder).
