Unformatted text preview: mportant properties: Linear system: Scale change: Modulation property: The Sampling Theorem: 1. Sampling a bandlimited (W) waveform (Sampling rate at least 2W samples/sec.) Reconstruction from samples: 2. Sending pulses through a bandlimited communication channel: response H(f) . If H(f) = 0 for *f*$ W, up to a maximum 2W pulses per second (bauds) can be sent through the channel. CHANNEL IMPAIRMENTS, LIMITATIONS Distortion - linear, nonlinear, Noise, Attenuation, Interference, limited frequency bandwidth LINEAR DISTORTION: H(f) = A(f)eJè(f) Combat with equalizer filter E(f), so E(f)H(f) has ideal filter characteristic.
