Acoustic Modem - Demodulator VHDL

[Iyury1]

Summary

The demodulator contains two bandbass filters for the mark and space frequency, two integrator blocks taking input from the bandpass filters, and a comparator to select which integrator output is larger, which indicators if a mark or a space was received.

Checklist

• Create VHDL entity for demodulator
• Determine frequency of mark and space and design bandpass filter entities
• Design itegrator entities
• Design comparator entity
• Instantiate components inside demodulator architecture
• Create testbench for demodulator
