摘要： A system and method that enables the collaborative creation and editing of content on a VoiceSite over a telephone. The system and method enables the collaborative creation and editing of content on the VoiceSite by allowing one or multiple users (authors) to generate and edit the content of the VoiceSite at the same or different times. A Collaboration Manager is utilized to manage calls to/from one or more users. A VoiGen component utilizes voice-activated prompts to allow the one or more users to perform at least one of specify user preferences, load templates, store user preferences and service options, parse through obtained data, and generate/edit the VoiceSite based on the inputs provided by the one or multiple users. A Session Manager stores user specific information and ensures that the content provided by multiple users, including edits/changes, is integrated without conflicts.

摘要： A dynamic element matching (DEM) scheme is implemented in a crawling code generator for converting a b-bit binary input code into a (2b−1)-bit digital output code. A random generator determines for every conversion step a direction. A decimal difference between the current and previous binary input is calculated. The new crawling output code is determined based on the previous crawling output code, the direction and the decimal difference. The DEM scheme is used in a digital-to-analog converter such that the crawling output code switches digital-to-analog converting elements that output analog signals that are then summed to be the final analog signal.

摘要： An offset free sinc interpolating filter includes differentiators operating at a first sampling frequency, integrators operating at a second sampling frequency and one or more coefficient multipliers. The coefficient multipliers multiply a received value with a constant coefficient value to generate an output value. The differentiators, integrators and coefficient multipliers can be operatively coupled to each other, either directly or through other components such as adders and delay elements, or by a combination of the two. In operation, an input signal is provided to the sinc interpolating filter at the first sampling frequency. The input signal is processed by the differentiators, integrators and coefficient multipliers to generate an output signal at the second sampling frequency. Once the output signal is generated, the integrators are reset before the next input cycle begins.

摘要： The invention may provide a method and filter block for compensating droop in a frequency response of a signal. The filter block may include a decimator, which decimates a high frequency input signal to a set frequency output signal. The set frequency can be, for example, the Nyquist frequency for the input signal. Further, the filter block may include a droop compensator that compensates the droop in the frequency response of the output signal from the decimator. The droop compensator may be made using recursive filters, as opposed to large tap FIR filters, which may result in less memory consumption and decreased power consumption.

摘要： A signal processor includes one or more memory banks, wherein each memory bank stores filter coefficients; and one or more coefficient multiplexer units; each coefficient multiplexer unit being associated with a memory bank, and retrieves a filter coefficient based on a number of received input samples. The processor includes one or more multiply and accumulate (MAC) units, each MAC unit being associated with a coefficient multiplexer unit and determines a product of the retrieved filter coefficient with an input sample; retrieves a previous value stored in an associated register; computes a summation of the previous value and the product; and stores the summation in the associated register. The processor includes an output multiplexer unit to select a register, and to provide a value stored in the register as an output.

User posts are appended to a category in a voice application and subdivision of the category is prompted upon satisfaction of a first condition. The category is designated as a parent category, and at least one subcategory nomination are solicited from users. User input is solicited on appending at least one nominated subcategory to the parent category, and a nominated subcategory is appended to the parent category upon satisfaction of a second condition. User input is solicited to reassign a user post from the parent category to at least one subcategory.
