Can you solve this question?
A digital information signal with a bit rate of 700 kbit/s is modulated onto a carrier wave with frequency fe using a binary modulation technique. The pulse shape used is rectangular. The modulated signal voltage can be written as: s (t) = = 75 cos (2π fct + 0.15 · ñ · d (t)) volt, where d(t) ɛ {−1, +1} during a symbol time. a. Determine the 2th null-null bandwidth of this transmitted BWn null_null Number kHz. signal. Ps= b. Calculate te power in this signal when delivered to a load resistor of 110 S2. c. What percentage of this signal power is transmitted as a carrier component? Number = %0-P car Number dBm %
