Scope of Learning

Delta Modulator & Demodulator

• Study and analysis of delta modulation and demodulation.
• Study and analysis of sample & hold output by varying the Sampling as well as signal frequency.
• Study and analysis of Integrator output at the modulator by varying the sampling frequency.
• Study and analyze the improved Integrator output by varying the gain control frequency.
• Understand slope overload distortion problem, granular noise problem
• Analyze single bit delta modulated PCM output, Integrator output at the demodulator.
• Analyze the final delta demodulated output with second order low pass Butterworth filter.

Adaptive Delta Modulator & Demodulator

• Study and analysis of adaptive delta modulation.
• Study and analysis of single bit PCM output by varying the sampling frequency.
• Analyze variable step register at the modulator side, accumulator and add/subtract at the modulator side.
