The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

You can use a 68HC11 and a 12-bit serial DAC (Figure 1) to generate accurate sine waves without using floating-point arithmetic. Figure 2 shows a block diagram for this sine-wave generator. You can ...
