Improved Error Estimates for First Order Sigma-delta Systems
نویسنده
چکیده
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 most O( 4=3+ ).

Second order Sigma-Delta (Σ∆) quantization of finite frame expansions ⋆
The second order Sigma-Delta (Σ∆) scheme with linear quantization rule is analyzed for quantizing finite unit-norm tight frame expansions for Rd. Approximation error estimates are derived, and it is shown that for certain choices of frames the quantization error is of order 1/N2, where N is the frame size. However, in contrast to the setting of bandlimited functions there are many situations wh...
متن کاملApproximating a Bandlimited Function Using Very Coarsely Quantized Data: Improved Error Estimates in Sigma-delta Modulation
This paper concerns fine analytical error estimates in analog-to-digital conversion of bandlimited functions using the method of sigma-delta modulation (also called Σ∆ quantization). This method has found widespread usage in practice due to several advantages in its implementation compared to conventional methods (see [1, 11]). A recent mathematical treatment of this problem appears in [3]. Bel...

In this thesis, our main focus is Sigma-Delta quantization schemes. These are commonly used in state-of-art Analog-to-digital conversion technology. Their main advantage is the ease of implementation and more importantly their insensitivity to certain circuit imperfections. When we compare sigmadelta scheme with pulse-code modulation (PCM), sigma-delta is inferior in terms of rate distortion be...

A MASH digital delta–sigma modulator (DDSM) is analyzed mathematically. It incorporates first-order error feedback modulators (EFM) which include prime modulus quantizers to guarantee a minimum sequence length . The purpose of this analysis is to calculate the exact sequence length of the aforementioned MASH DDSM. We show that the sequence length for an th-order member of this modulator family ...
متن کاملNumber theoretical error estimates in a quantization scheme for bandlimited signals
Sigma-delta quantization is a way of representing bandlimited signals (functions with compactly supported Fourier transforms) by {0, 1} sequences for each sampling density such that convolving these sequences with appropriately chosen filters produces approximations of the original signals. Approximations are refined by increasing the sampling density; this is what makes such a scheme fundament...
