Analog and Digital Communications Laboratory Experiments Using Emona TIMSAbstractIn 2007 our electrical engineering program adopted a required principles of communicationscourse with a weekly two-hour laboratory. Laboratory experiments were developed using theEmona TIMS communications modules, covering analog and digital communications conceptssuch as double sideband – suppressed carrier (DSB-SC); amplitude modulation (AM); frequencymodulation (FM); sampling, quantization, and pulse-code modulation (PCM); amplitude,frequency, and phase shift keying (ASK, FSK, PSK); and bit error rate for a baseband digitalsignal in the presence of noise. Another experiment currently in preparation involves directsequence spread spectrum (DSSS) and code-division multiple access (CDMA). This paperpresents an overview of the experiments that have been developed, including some features ofthe experiments that are not in the TIMS manuals. The paper also discusses how theseexperiments have helped the students visualize communication-system concepts.
