MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Bit rate is a measure of the number of data bits (that’s 0’s and 1’s) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation ‘bps’. Baud rate by definition means the number of times a signal in a communications channel changes state.

Detailed explanation-2: -Baud unit symbol “Bd is synonymous to symbols per second or pulses per second. It is the unit of symbol rate, also known as baud or modulation rate; the number of distinct symbol changes (signaling events) made to the transmission medium per second in a digitally modulated signal or a line code.

Detailed explanation-3: -; The data transmission from the 8051 will be at a Baud rate of 4800 bps.

Detailed explanation-4: -In serial communication, data is transmitted one bit at a time (Figure 4.20a). Thus if an 8-bit word is to be transmitted, the 8 bits are transmitted one at a time in sequence along a cable.
