Digital Block For A Fucntion Generator
Beginning of paper
The Digital Block is the heart of this digitally controlled function generator. Symmetry and frequency variation is direct result of the design of this block. In this design the emphasis was on simplicity and some target specifications at the top of the frequency variation were compromised in order ....
Middle of paper
.... inputs controlling frequency and symmetry are also built into this control block.
Therefore it is clear that the digital block can be divided into 4 distinct blocks, each with its own functionality. These blocks are the control module, counter module, filter control module and 8-bit D/A. The D/A chosen is the DAC0801LCN. It’s specifications can be found in the appendix. The layout of this design is shown below.
The interconnections will be discussed later but the thic ....
