摘要： The present invention has an object to provide a sampling filter apparatus and a wireless communication apparatus, which are capable of changing a filter characteristic without employing complex waveforms as control signals, and also, capable of performing filtering process operations without performing a decimation, while utilizing a wide frequency space. A sampling filter apparatus 100 includes a controller 140, a plurality of integrators 150 to 154, a plurality of switches 130, 160 to 164, 170 to 174, 180 to 184, and a plurality of voltage/current converters 120 to 123. An inputted current is stored in four pieces of integrators selected among the plurality of integrators 150 to 154 by one clock, and electric charges which have been stored from four preceding clocks up to one preceding clock are added to each other so as to output the added electric charges from the remaining one integrator. When electric charges are stored in the integrators 150 to 154 in each clock, since the inputted current is switched, the electric charges to be outputted can be weighted, and thus, a filter characteristic is changed.

摘要： The present invention aims at providing a sampling filter capable of changing a filtering characteristic without use of a complicate waveform as a control signal. A sampling filter 100 has a control section 140, a plurality of integrators, and a plurality of switches. An input current is accumulated in a plurality of capacitors in one clock; adds up electric charges accumulated in the integrators in several preceding clocks to one preceding clock; and outputs a result of addition. When electric charges are accumulated in the integrators in each clock, output electric charges can be subjected to, while being weighted, addition by switching an electric current to be input, so that the filtering characteristic is changed.

摘要： Provided is a digital filter for radio communication processing capable of dynamically modifying the characteristic and simultaneously processing a plurality of systems. In the digital filter, calculation core groups (1010-1017) capable of modifying function are arranged and connected to one another by an input interface unit (102) and an output interface unit (103).
