Need help with questions 1-2.thanks

1. Problem 1 (20 points) Consider a bandpass digital communication system using a carrier frequency of 600 khz as the modulation technique a) Draw the waveform corresponding to the data sequence 1101001 if ASK is chosen as the modulation technique. b) Draw the waveform corresponding to the data sequence 1101001 if PSK is chosen as the modulation technique c) Draw the waveform corresponding to the data sequence 1101001 if FSK is chosen as the modulation technique and frequency offset is 100kHz 2. Problem 2 (20 points) Using the transmission speeds, carrier frequencies, and frequency offset from problem 1, draw the average normalized power spectra for typical transmitted ASK, PSK, and FSK waveforms
