- The reflections of electrical pulses along the conductor are studied and measured by TDR.
- It passes down the cable pair and incident signals & listens for the reflections.
- There’ll be no reflection if the cable pair has an invariable impedance, and the incident signals will be received at another end of the cable pair.
- If the cable pair is not of unvarying impedance, then a number of the incident signal would be transferred to the TDR that tracks the fault after analyzing the reflections.
Second Full form of TDR
Another full form of TDR is Term Deposit Receipt. It describes an account that holds a deposit for a specific period. It occasionally goes by the name of a fixed deposit scheme. TDR offers a higher rate of interest than other kinds of savings accounts.
TDR often functions as a short-term deposit. Its lifespan ranges from a few months to a few years, and the money can only be withdrawn when the predetermined time period has passed. Financial institutions, such as credit unions, banks, and thrift institutions, offer TDR and other related financial products.
