【 摘 要 】

References(4)Cited-By(2)We propose two approximations of the inverse wavelet transform implemented with a voltage adder and two analog filters. They work together with a set of scaled band-pass analog filters that perform the wavelet transform of a continuous time signal. With this approach an integrated circuit has been fabricated. On-chip measurements demonstrate signal to reconstruction error ratios up to 25.8dB.
