PCM | Delta modulation |
---|---|
1] Pulse code modulation has sample-quantize and encode mechanism. | 1] Delta modulation has sample-compare and encode mechanism. |
2] It requires n bits per sample, depending upon accuracy. | 2] It requires a single bit per sample. |
3] Band width required is more as compared. | 3] Band width required is less as compared. |
4] Quantization error is present. | 4] slope over load & granular noise is present. |
5] Since, more number of bits are present, power requirement is large. | 5] Since less number of bits are present, power required is less. |
