本文首次提出了三态自适应增量调制编码方法。通过对图象信号进行编码和滤波的模拟研究
证明了这种三态ADM编码的动态范围比二态ADM编码增大6—10dB
信噪比改善约为1.5—3.5dB
并保持了可实现无乘法滤波的特点。
In this paper
Tri-state adaptive delta modulation is presented for the first time. By simulations of image coding and filtering
it is proved that the dynamic range of Tri-state ADM is 6~10dB larger and the signal-to-noise ratio is 1.5~3.5dB better than conventional Two-state ADM while its filtering without multiplication is maintained.
