This document presents a comprehensive solution to an electrical engineering assignment. The assignment covers a range of topics, including converting binary data into analog waveforms using various modulation techniques (ASK, FSK, PSK, DPSK, QAM), frequency computation, drawing analog and frequency modulation waveforms, constructing a 16 QAM constellation diagram, explaining and drawing the Cyclic Redundancy Check (CRC) error detection process, computing the frame check sequence, calculating the transmitted signal using Direct Sequence Spread Spectrum, differentiating between Infrastructure and ad hoc modes in WLAN, and comparing TCP and OSI protocols for wired and wireless LANs. The solution includes diagrams and explanations to illustrate the concepts and calculations involved in each problem, providing a thorough understanding of the subject matter.
