The QSICOS-software has been developed to help to obtain an optimized set of
coefficients both quickly and easily. The QSICOS program runs on any PC with at least
575 Kbytes of memory. This also requires MS-DOS Version 5.0 or higher, as well as
extended memory.
Semiconductor Group
• For line equalization and compensation of attenuation distortion
• Improvement of Group-Delay-Distortion by using minimum phase filters
• FRR filter for correction of receive path distortion
• FRX filter for correction of transmit path distortion
• Frequency response better 0.1 dB
• Improved level adjustment for transmit and receive
• Two separate filters at each direction for
(instead of linear phase filters)
– 5 TAP programmable FIR filter operating at 8 kHz
– 5 TAP programmable FIR filter operating at 8 kHz
– Improved trans-hybrid balancing
– Optimal adjustment of digital dynamic range
– Gain adjustments independent of TH-filter
