Forward Error Correction (FEC) FEC is a technique used to detect and correct errors in transmitted data without the need for retransmission. FEC involves adding redundant information (parity bits or error-correcting codes) to the transmitted data. This redundant information allows the receiver to detect and correct errors without requiring the sender to resend the data. … Read more
Electromagnetic interference (EMI) refers to the disturbance caused by electromagnetic radiation on electronic devices, equipment, or systems. This interference can disrupt the proper functioning of electronic devices and cause issues such as signal distortion, data corruption, increased error rates or even complete failure. EMI can occur through mechanisms such as radiation from electronic devices, power … Read more
