Analog and digital communication systems are fundamental to modern information transmission, enabling the reliable delivery of voice, data, and multimedia over communication channels. Their operation relies on concepts such as modulation, demodulation, spectral analysis, pulse modulation, digital signaling, multiplexing, and the effects of channel impairments. Although these concepts are introduced mathematically in lectures classes, understanding how the transmitted and received signals behave in the time and frequency domains is often easier through experimentation and visualization. The Analog and Digital Communication Lab provides a simulation-based environment for exploring these principles through a sequence of eleven experiments. The sequence begins with mathematical and signal-analysis tools, including matrix operations and Fourier-based analysis, and then examines the statistical response of systems to wide-sense-stationary inputs. It proceeds to analog amplitude, frequency, and phase modulation; suppressed-carrier modulation schemes such as DSB-SC and SSB-SC; and pulse modulation techniques including PAM, PWM, PPM, and delta modulation. The digital communication experiments cover ASK, FSK, and BPSK generation and detection, including their passband implementations, followed by the study of channel effects and modulation schemes with memory such as MSK and GMSK. The final experiment addresses frequency/time-division multiplexing concepts. Together, these experiments connect the mathematical representation of signals with the practical operation of communication-system building blocks. Students can observe modulation and demodulation processes, examine signal spectra, compare digital signaling schemes, and investigate how channel conditions influence system behavior. The lab is intended to complement classroom teaching with guided, hands-on simulation.
