谁帮我用英文翻译下这段话，关于滤波器的

The system has four modules: program-controlled amplifiers, programmable filters, fourth-order elliptic low pass filter, and amplitude-frequency characteristics of simple tester. Programmable amplifier voltage gain 60dB, gain 10db step adjustable voltage gain error is less than 5%. Pass band 100HZ ~ 200KHz, the amplifier output without significant distortion. The core of the program-controlled by the MAX262 filter can be set to low pass, high pass filter,-3dB at 1KHz ~ 20KHz frequency range of adjustable, adjust the frequency step is 1KHz. Fourth-order elliptic low pass filter, band fluctuations ≤ 1dB,-3dB passband to 50kHz, required amplifier and low pass filter in the 200kHz office is less than the total voltage gain 5dB,-3dB passband error is less than 5%. Simple amplitude-frequency characteristics of the frequency sweep signal tester to set the output range of 100Hz ~ 200KHz, frequency 100Hz adjustable step. AT89S52 as the control system to the core, has been tested and verified, the system is stable, easy to operate.
