 Which types of waveform can be generated by the M_Functions ?
The M_Functions use wave-form-image-data format to reconstruct the output waveform.
Therefore nearly any types of waveform can be generated. The only limitations are resolution and
frequency. It is very difficult to generate a very high resolution and high frequency waveform in a
multi-task OS.
If the user want to generate the periodic wave form such as sine, cosine,...., the M_Functions can
provide the output wave form over 100 k Samples/sec. The
Figure 8-3 and 5 V 200 kS/s sine wave shown in Figure 8-4 are all generated by M_Function1. The

Figure 8-3 and Figure 8-4 is measured by Tektronix TDS 220. The display resolution of TDS 220 is
limited, so the output waveform does not look smooth. The real output waveform is smooth.
