2.1.3 Pulse-Shaping Filter
2.1.4 Analog CT Reconstruction Filter
2.1.5 Line Driver
2-4
The pulse-shaping filter is used to filter the quats output from the variable-gain
DAC. This filter, when combined with other filtering in the signal path, produces
a transmitted signal on the line that meets the power spectral density, the
transmitted power, and the pulse-shaping requirements, as specified in
Chapter 5.0, Electrical and Mechanical
The analog CT reconstruction filter removes the discrete-time images from the
transmit signal before it is amplified by the line driver.
The line driver buffers the output of the CT reconstruction filter to drive diverse
loads. The output of the line driver is differential.
