Analog Implementation of Ratio Spectrum Computation
نویسندگان
چکیده
A novel transform space called the ratio spectrum has been developed. The ratio spectrum is formed by plotting the ratio of the power of a low-pass filtered signal to the power of the original unfiltered signal vs. the filter cutoff frequency. The spectrum is necessarily a monotonic function of frequency that is bounded between zero and one. Though we prove that this transform space is mathematically equivalent to the power spectrum of a signal, the ratio spectrum provides a number of computational advantages. One major advantage is that analog hardware can efficiently compute the ratio spectrum. Measured results from such an analog VLSI implementation are discussed in this paper.

This brief presents a time-domain approach for the implementation and continuous generation of wavelet transform coefficients for spectral analysis applications. The wavelet generation relies on amplitude modulation techniques. This approach offers two extra degrees of freedom through the appropriate use of the modulation index and the selected envelope signal. The added flexibility along with ...
متن کاملAnalog Versus Digital: Extrapolating from Electronics to Neurobiology
We review the pros and cons of analog and digital computation. We propose that computation that is most efficient in its use of resources is neither analog computation nor digital computation but, rather, a mixture of the two forms. For maximum efficiency, the information and information-processing resources of the hybrid form must be distributed over many wires, with an optimal signal-to-noise...

This paper addresses the use of Analog Behavioral Models (ABMs) in an efficient strategy for designing analog emulation engines for large scale power system computation. Through discussion of historical development of analog computation in power system analysis and its present resurgence, we present the need for, and application of ABMs for model verification and validation prior to full struct...

Nonlinear processing is often more suitable than the traditional linear approach is for analyzing biological signals. Unfortunately, digital nonlinear operations are computationaly expensive. In contrast, a large variety of nonlinear operations can efficiently be implemented in analog electronics, operating at real-time speeds. The low level of accuracy generally associated with analog processi...
