Digital function generator (2):

The only connection between the PLL board and the discretely designed analogue parts of the generator is via plugs and sockets K2. K5 and K8. Pin 1 of these connectors carries the 32 Hz- 3.2 MHz clock, which isconverted in the various sections to a 1 Hz- 100 kHz sinusoidal, reetangular or triangular signal. The other pins carry information about the selected decadic range.
