A frequency 5kHz higher is input via the data bus, that is to say 15350600 (addr.
4: 1535, addr. 5: 0600). MHz value is added to the constant of the N divider. The
total of 54 (39 + 15) is the N value. The 100kHz value of the frequency is added
to the constant for the A divider. The total of 11 (8 + 3) is the A value.
Value R is 10 for all frequencies. The values for A, N, and R are supplied to syn-
thesizer module D6 in loop 2 with 8 addressed 4-bit words via the lines DOUT0
to DOUT3, AOUT0, AOUT1, AOUT2, and Divider (Ref. Fig. 13).
The value of the frequency from the 10kHz point is added to the constant for
DDS. The total of 270.6kHz (220 + 50.6) is the frequency that is then generated
in the DDS.
The data of a digitized sinusoidal oscillation are stored in EPROM D26. The ad-
dresses for these data are determined in the gate array. The sinusoidal values
are supplied to the D/A converter via latch D24.
