delta stigma modulation

The unit is one of a range of digital communication trainers and provides all necessary inputs and connections for students to study Delta, Adaptive Delta and Delta Sigma Modulation Demodulation. The 7405 covers the concepts of delta modulation demodulation, slope overloading, adaptive delta modulation demodulation, sigma delta modulation demodulation and amplitude overloading.

Experiments:

• Study of delta modulation & demodulation
• Study of adaptive delta modulation & demodulation
• Study of delta sigma modulation & demodulation

Key Features

• Transmitter and receiver on same board
• Clock generation from crystal
• Switch selectable sampling rates
• 4 on-board generators at 4 different frequencies (synchronized)
• Separate adjustable DC level
• Selectable integrators gain setting (by switch or control circuit)
• On-board 4^th order Butterworth low pass filter
• Unipolar to bipolar conversion on-board
