California State Polytechnic University, Pomona Department of Electrical and Computer Engineering ECE 405L Electronic Communications Laboratory Experiment #2 Properties of On-Off-Keyed (OOK) Periodically Gated Waveforms Objective: To investigate the mathematical and actual properties of on-off keyed periodically gated waveforms (the simplest digital signal) using common electronic communications laboratory equipment. Pre-lab: Calculate the Fourier spectrum the following waveforms: a) A sine-wave with a total period of 1 microsecond with a peak amplitude of 1000 mV. b) A square-wave with a total period of 100 us with a

Unformatted text preview: peak amplitude of 1 volt. c) A rectangular wave with duty cycle of 0.25 and a total period of 100 us with a peak amplitude of 1 volt. d) The product of mixing the waveform in part A with the waveform in part B. Lab: Using the equipment in the laboratory, measure and record the time and frequency (using both the continuous series and discrete transform) domains for each waveform described in the pre-lab. Post-Lab: In your report explain the differences between your calculated and your measured values....
