Signal frequency bandwidth limitation, fast pulse shaping, separation between telecommunications signals, and suppression of unwanted carrier and disturbance frequencies are among the most important jobs of filter circuits. While active filters with operational amplifiers and switched capacitor filters are used for lower frequency applications, passive filter versions dominate the application spec

Coax cables with a typical impedance of 50О© or 75О© are used in many applications to ensure signal fidelity, and high-speed line drivers have the often difficult job of transmitting signals over these cables or over twisted pair lines. The most common way to drive coax cables is to use driver amplifiers with low-impedance voltage output, which operate with either voltage or current feed
