The symbol duration time T s can be calculated as: = where f s is the symbol rate. For example, a baud rate of 1 kBd = 1,000 Bd is synonymous to a symbol rate of ...
The unit interval is the minimum time interval between condition changes of a data transmission signal, also known as the pulse time or symbol duration time.A unit interval (UI) is the time taken in a data stream by each subsequent pulse (or symbol).
The symbol duration time T s can be calculated as: =, where f s is the symbol rate. There is also a chance of miscommunication which leads to ambiguity. Example: Communication at the baud rate 1000 Bd means communication by means of sending 1000 symbols per second.
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world , is the second , defined as about 9 billion oscillations of the caesium atom.
In the International System of Units (SI), the unit of time is the second (symbol: s). It has been defined since 1967 as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom", and is an SI base unit.

Since the duration of each symbol is long, it is feasible to insert a guard interval between the OFDM symbols, thus eliminating the intersymbol interference. The guard interval also eliminates the need for a pulse-shaping filter , and it reduces the sensitivity to time synchronization problems.
The symbols Δt and ΔT (spoken as "delta T") are commonly used in a variety of contexts. Time. ΔT (timekeeping) the difference between two time scales, ...
The period (symbol T) is the interval of time between events, so the period is the reciprocal of the frequency: T = 1/f. [ 2 ] Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals ( sound ), radio waves , and light .
