Lifeline signals are visual or auditory signals used to indicate distress or the need for assistance, particularly in emergency situations. These signals can include hand signals, flares, whistles, or emergency beacons. In various contexts, such as outdoor activities or maritime operations, they serve to alert others to a person's urgent need for help. Effective use of lifeline signals can significantly enhance safety and improve the chances of timely rescue.
The Lifeline program was initiated by the Federal Communications Commission (FCC) in 1985. It was designed to provide affordable telephone service to low-income individuals and families in the United States. The program aims to ensure that all Americans have access to essential communication services, particularly in emergencies. Over the years, Lifeline has expanded to include discounts on broadband services as well.
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
The two types of signals commonly converted and displayed on a Digital Multimeter (DMM) are direct current (DC) signals and alternating current (AC) signals. DC signals represent a constant voltage or current level, while AC signals vary in magnitude and direction over time. DMMs can measure voltage, current, and resistance in both types of signals, providing versatile functionality for electrical measurements.
