Abstract: A bandpass sigma-delta modulator using acoustic resonators or micro-mechanical resonators. In order to improve resolution at high frequencies, acoustic resonators or micro-mechanical resonators are utilized in a sigma-delta modulator instead of electronic resonators. The quantized output is fed back using a pair of D/A converters to an input summation device. In fourth order devices, the feed back is to two summation devices in series. Such a sigma-delta modulator is usable in a software defined radio cellular telephone system and in other applications where high-frequency and high-resolution A/D conversion is required.

Abstract: In some embodiments, the inventions includes a transmitter including a cycle encoding circuit to receive a data input signal and to provide a full cycle encoded signal in response thereto by continuously joining portions of different encoding signals. Some of the encoding signals have a different frequency than others of the encoding signals and some of the encoding signals have a different phase than others of the encoding signals. Data is represented in data time segments of the full cycle encoded signal and no data time segment has more than one cycle of an encoding signal. In some embodiments, a receiver receives the cycle encoded signal and recovers data of the data input signal.

Abstract: Methods to test the operation of the pick-up coil without having to de-energize the power line serving as the power line carrier in order to perform testing on the pick-up coil. A series of test frequencies are introduced and parameters of the pick-up coil can be measured to detect the presence or absence of resonant behavior indicative of the health of the pick-up coil. Testing capabilities may be incorporated into a power line carrier receiver and use the connections between the pick-up coils and the receiver to perform the pick-up coil test. Various methods are disclosed for evaluating the pick-up coil response to a series of test inputs of different frequencies. These methods could be incorporated in a pick-up coil testing device that is independent of a receiver.

Abstract: A method and unit for substracting quantization noise from a pulse code modulated PCM signal being segmented into frames. For achieving this it is proposed to first calculate for each frame of the PCM signal a quantization noise level Bq according to an equation having parameters including n which indicates a specific sample of the PCM signal, S*min[n] which represents the minimum quantization noise level for a specific sample value s*[n] of the PCM signal, S*max[n] which represents the maximum quantization noise level for the specific sample value s*[n] of the PCM signal, w[n] which represents a window-function and W which represents the number of samples per window. Subsequently, the quantization noise as represented by the quantization noise level Bq has to be substracted from the PCM signal, preferably with the help of a suitable background noise substracting system. B q = ∑ n = 0 W - 1 { ( s min * [ n ] - s max * [ n ] ) · w [ n ] } 2 12 ( I )
