A 10 kbps binary information data signal is required to be transmitted using ASK digital
modulation technique. Determine the minimum bandwidth and baud rate necessary
The minimum bandwidth, BASK (minimum) = fb
where fb is the binary information bit rate.
For given fb = 10 kbps,
BASK (minimum) = 10 kHz
We also know that in binary ASK digital modulation technique, 1 symbol = 1 bit
For given fb = 10 kbps,
baud rate = fb = 10 ksymbols/sec.
A 1000 bps binary information data signal is required to be transmitted in half-duplex mode using
BFSK digital modulation technique. If the separation between two carrier frequencies is 3000 Hz,
determine the minimum bandwidth of the BFSK signal.
