Calculate the bit rate for the given baud rate and type of modulation.
a) 1000 baud, FSK
b)1000 baud,ASK
c)1000 baud, BPSK
d)1000 baud, 16-QAM
a) Bit rate for 1000 baud FSK is 2 * 1000 = 2000 bits per second.
b) Bit rate for 1000 baud ASK is 1 * 1000 = 1000 bits per second.
c) Bit rate for 1000 baud BPSK is 1 * 1000 = 1000 bits per second.
d) Bit rate for 1000 baud 16-QAM is 4 * 1000 = 4000 bits per second
How can one calculate the bit rate for baud rate for the modulation types FSK, ASK, BPSK, and 16-QAM?The bit rate for a given baud rate and modulation type can be calculated as follows:
FSK: Bit rate = 2 * Baud rate
This is because in FSK, two different frequencies are used to represent the binary data (0 and 1), so for each baud, two bits of data can be transmitted.
ASK: Bit rate = 1 * Baud rate
This is because in ASK, only one frequency is used, and the amplitude of the carrier signal is changed to represent the binary data. For each baud, one bit of data can be transmitted.
BPSK: Bit rate = 1 * Baud rate
This is because in BPSK, only one frequency is used, and the phase of the carrier signal is changed to represent the binary data. For each baud, one bit of data can be transmitted.
16-QAM: Bit rate = 4 * Baud rate
This is because in 16-QAM, four bits of data can be encoded in each symbol period. For each baud, 4 bits of data can be transmitted.
Therefore, the correct answers are as given above.
