bitperiod
Bit period, denoted Tb, is the time duration of a single bit in a digital communication system. It is the reciprocal of the bit rate Rb, measured in bits per second: Tb = 1 / Rb seconds. Thus, increasing the bit rate shortens the bit period. The bit period establishes the fundamental timing for sampling the received signal and for shaping transmitted pulses. In systems where each symbol carries exactly one bit, the bit period equals the symbol period and the baud rate equals the bit rate.
If symbols encode more than one bit, the relationship changes. Let k be the number of bits
