CAT NO: DIDACTICECE-LAB-0070
Coding 7AMI/HDB3/CMIDATA Terster.
INTRODUCTION
MCM33/EV is one of the experiment boards that constitute the
Interactive Practical Electronics System – I.P.E.S.
It consists of a set of components and circuits for performing experiments.
The lessons included in this module can be developed in:
- Standard mode: using the switches of the equipment and
consulting the handbook;
- Computerized mode: the interactive software version of
the handbook - interfaced to the module
via Control unit, is used. This software inserts circuit
variations and faults automatically enabling the development
of lessons even without teacher’s assistance.
TRAINING PROGRAM:
• Discrete input source
• Channel coding (error control)
• Line coding and precoding importance
• Transmission and reception filter (spectrum modeling)
• Effects of the characteristic of the transmission line
• Intersymbol interference
• Eye diagram
• Data extraction
• Synchronism recovery
• Sampling of the received signaling pulses
• Error rate calculation
• Analysis of the Fourier spectrum of the signal present in the
main points of the transmission and reception system, to
observe the characterization and the
modifications of the
same spectrum
• Digital Signal Processing: description of the schematic
diagram and operating modes of a specific microprocessor
for digital signal processing
• Troubleshooting
