摘要： A continuously or step variable passive noise filter for removing noise from a signal received from a DUT added by a test and measurement instrument channel. The noise filter may include, for example, a splitter splits a signal into at least a first split signal and a second split signal. A first path receives the first split signal and includes a variable attenuator and/or a variable delay line which may be set based on the channel response of the DUT which is connected. The variable attenuator and/or the variable delay line may be continuously or stepped variable, as will be discussed in more detail below. A second path is also included to receive the second split signal and a combiner combines a signal from the first path and a signal from the second path into a combined signal.

摘要： (Problem) To provide a charge sampling filter circuit and a charge sampling method.
(Means for resolution) A charge sampling filter circuit includes a first capacitor that samples an input signal, and in which at least a portion of electric charge stored in the first capacitor by sampling is output to a second capacitor that is connectable with the first capacitor. The charge sampling filter circuit is characterized by including a switching portion that switches a circuit mode including a sampling mode that causes the first capacitor to sample the input signal, and an output mode that causes the first capacitor and the second capacitor to be connected. A capacitance value of the first capacitor in the output mode is set to be lower than the capacitance value in the sampling mode.

摘要： An elementary cell structure for programmable time-continuous analog filters and in particular for the processing of analog signals in read/write operations on magnetic supports comprises an amplifier stage (3) provided with a pair of structurally identical transconductance half-cells (2,2') connected together in a common circuit node (X).
With a cascade of cells of this type is provided a time-continuous analog delay line which is used in a transverse time-continuous analog filter. This filter comprises a cascade of identical delay lines (LR) connected through multiplier nodes (5) to a final summation node (6).
