NOTES:
- These figures are for the
entire stereo generator/Composite Processor/transmitter
system. It is assumed that the system was within the limitations
of FCC Rules before installation of the CP-803. All
figures are typical.
- Systems having nonlinear crosstalk
of worse than –45
dB before installation of the CP-803 may not meet these specifications
at all frequencies.
- All noise and distortion components
from 20 Hz to 80 kHz were measured.
