We propose a neuromorphic architecture for real-time processing of acoustic transients in analog VLSI. We show how judicious normalization of a time-frequency signal allows an elegant and robust implementation of a correlation algorithm. The algorithm uses binary multiplexing instead of analog-analog multiplication. This removes the need for analog storage and analog-multiplication. Simulations...

Analog synthesizers continue to be used by many musicians because of their distinctive timbres, intuitive real-time control and flexible patching. There has been recent interest in simulating the analog signal chain with digital techniques. However, a literal time-domain translation of analog VCOs and VCFs is surprisingly challenging. This paper presents a new strategy for digital simulation ba...

We introduce a model for analog computation with discrete time in the presence of analog noise that is exible enough to cover the most important concrete cases, such as noisy analog neural nets and networks of spiking neurons. This model subsumes the classical model for digital computation in the presence of noise. We show that the presence of arbitrarily small amounts of analog noise reduces t...

Analog soft iterative error control decoders use analog computation to decode digital information. Analog soft-information processors offer the power of iterative decoding with a very small transistor count, enabling fully parallel decoding at low cost. They can be implemented in several technologies: BiCMOS and SiGe analog decoders are suitable for high-speed applications beyond 10 Gbit per se...

We introduce a model for noise-robust analog computations with discrete time that is exible enough to cover the most important concrete cases, such as computations in noisy analog neural nets and networks of noisy spiking neurons. We show that the presence of arbitrarily small amounts of analog noise reduces the power of analog computational models to that of nite automata, and we also prove a ...
