A direct-sequence spread-spectrum system uses FSK with a chipping rate of 20 to 1. The signal-to-noise ratio for the spread signal is −5 dB (that is, the signal is 5 dB weaker than the noise in the same bandwidth). If the data is transmitted at 50 kb/s, calculate:
a. The chipping rate
b. The bandwidth occupied by the spread signal
a. The chipping rate
b. The bandwidth occupied by the spread signal
