    • The present invention generally relates to an apparatus and method for efficiently summing the partial product bits produced by a multiplier. Briefly described, in architecture, the apparatus includes a first array of odd/even summation circuitry, a second array of odd/even summation circuitry, and a linear array of adders. The apparatus is configured to add a row of partial product bits produced by a multiplier in multiplying a first operand with a second operand. The first array of odd/even summation circuitry produces a first summation of a portion of the partial product bits. The second array of odd/even circuitry produces a second summation of the other partial product bits. The linear array of adders then adds the first summation and the second summation to produce a carry save representation of a product bit (i.e., a bit of the product produced by multiplying the first operand by the second operand).

    • A capacitive sensor system including a sensing plate, an amplifier, and a switching circuit is described. The sensing plate is capacitively coupled to a body surface. A change in the electric potential on the body surface generates an electric field that induces change in the electric potential of the sensing plate. The sensing plate includes a sensing node positioned in the electric field for generating an input signal from the electric field. The sensing plate is not in contact with the body surface. The amplifier receives the input signal at the input port, amplifies the input signal and generates an output signal at the output port. The switching circuit is connected to the input port and a reference voltage. The switching circuit non-continuously closes a shunting path from the sensing node to the reference voltage to reset the voltage at the sensing node.

    • An electronic filter for filtering an electrical signal. Signal processing circuitry therein includes a logarithmic filter having a series of filter stages with inputs and outputs in cascade and respective circuits associated with the filter stages for storing electrical representations of filter parameters. The filter stages include circuits for respectively adding the electrical representations of the filter parameters to the electrical signal to be filtered thereby producing a set of filter sum signals. At least one of the filter stages includes circuitry for producing a filter signal in substantially logarithmic form at its output by combining a filter sum signal for that filter stage with a signal from an output of another filter stage. The signal processing circuitry produces an intermediate output signal, and a multiplexer connected to the signal processing circuit multiplexes the intermediate output signal with the electrical signal to be filtered so that the logarithmic filter operates as both a logarithmic prefilter and a logarithmic postfilter. Other electronic filters, signal conversion apparatus, electroacoustic systems, hearing aids and methods are also disclosed.
