# 1. Convert the binary data “110101” into analog waveforms

1. Convert the binary data “110101” into analog waveforms using following modulationtechniques:a. Two level Amplitude Shift Keyingb. Two level Frequency Shift Keyingc. Two level Phase Shift Keyingd. Differential Phase shift keyinge. Four level Amplitude Shift Keyingf. Four level Phase Shift Keyingg. Eight level Amplitude Shift Keying2. With fc = 1000 kHz, fd = 50 kHz, and M = 16 (L = 4 bits), using Multiple Frequency-ShiftKeying (MFSK), compute the frequency assignments for each of the sixteen possible 4bit data combinations. 3. Draw the approximate Analog Modulation and Frequency Modulation waveforms incomplete steps for the following signal:4. Draw the 16 QAM Constellation Diagram having four different amplitude levels and fourdifferent phase levels.5. Explain and draw the Error Detection Process for Cyclic Redundancy Check (CRC).6. Compute the frame check sequence using Cyclic Redundancy Check (CRC) for thefollowing information:Message = 111010110, Pattern = 1011107. Compute the transmitted signal using Direct Sequence Spread Spectrum for thefollowing information:Input: 101, Locally Generated PN bit stream: 011011010110, T = 4Tc8. Explain why the square and circle shapes cells for cellular communications are notappropriate as compared to hexagonal shape cells.
