Question 4 (a) A 3,000 bit/second data terminal is connected to a modem with 25% raised-cosine roll-off pulse shaping is used. Calculate the transmission bandwidth Bt required at the modem output for each of the following schemes: (0) Binary amplitude-shift keying (ASK) transmission. [2 marks] (ii) Binary frequency-shift keying (FSK) transmission with a frequency deviation of +2,400 Hz around the carrier. [2 marks] (iii) 16-level quadrature amplitude modulation (QAM).

hi can you help me solve this question?..thank you.. A Quadrature Phase Shift Keying (QPSK) modulator has a carrier frequency of (b) 10GHz is used to send data at a rate of 500Mbps over a satellite communication system. The satellite's transponder has a bandwidth of 300MHZ and the measured received signal-to-Gaussian-Noise (power) ratio at the receiving ground satellite is 30dB. If the satellite signal is equalized to have an equivalent raised cosine filter characteristic, determine the transponder's: roll-off factor )...
