System Frequency Characteristics
Figure 6 shows a typical, response curve of the Pre-Process Path, in receive mode, set against the
device specification. The general characteristic shape is produced by the Input Highpass and Lowpass
Filters, without the internal pre-emphasis element.
Figure 7 shows a typical response curve of the Post-Process Path set against the device specification.
The general characteristic shape is produced by the Post-Deviation Limiter Filter, without the de-
emphasis element.
