| Abstract: | This system consists of three large blocks such as the preamplifier,the network with resistance and the digital-frequency equalizers.The preamplifier can reach the demands of increasing benefits through the application of amplifying circuit with the multi-stage identical proportion,which is made up of integrated operational amplifiers.The network with resistance can meet the requirements of attenuation by the adjustment of partial parameters of circuit.And the digital-frequency equalizer can realize the fre... |
