Improved Error Estimates for First Order Sigma-delta Systems
A sigma-delta modulator converts a sequence of real numbers bounded by 1 into a digital sequence with entries +1 and 1 only. When the input sequence consists of samples of a bandlimited function, oversampled by a factor with respect to its Nyquist frequency, we prove that filtering the digital output with an appropriate kernel reproduces the original bandlimited function up to an error of at mo...
متن کاملCoefficient estimates for a class of meromorphic bi-univalent functions
Article history: Received 23 April 2013 Accepted after revision 21 May 2013 Available online 30 May 2013 Presented by the Editorial Board Applying the Faber polynomial coefficient expansions to a class of meromorphic biunivalent functions, we obtain the general coefficient estimates for such functions and also examine their early coefficient bounds. A function univalent in the open unit disk is...
متن کاملCoefficient Estimates of Meromorphic Bi- Starlike Functions of Complex Order
In the present investigation, we define a new subclass of meromorphic bi-univalent functions class Σ′ of complex order γ ∈ C\{0}, and obtain the estimates for the coefficients |b0| and |b1|. Further we pointed out several new or known consequences of our result.
متن کاملCoefficient Estimates in Subclasses of the Carathéodory Class Related to Conical Domains
We study some properties of subclasses of of the Carathéodory class of functions, related to conic sections, and denoted by P(pk). Coefficients bounds, estimates of some functionals are given.
متن کاملLow-Area 4th-Order Shared-Amplifier Sigma-Delta Modulator
Analog-to-digital converters provide a vital interface in mixed-signal electronic systems. One of the typical approaches to implement high-resolution sigma-delta modulators often involves the choice of high-order loop-filters, which imply the use of a large number of integrators. As in common topologies each integrator is implemented by one operational amplifier, high-order modulators can deman...
