Signal generators
Signal qualities
The quality of the signal is determined by the numbers of sampling points, which means the number of calculation cycles. The minimal cycle time of a task (program) is predefined by the minimal cycle time of the target system.
So, the interrelationships can be described as follows:
The influence of the sample rate can be illustrated by the following two figures of a sine wave signal:
- frequency = 2Hz
- cycle time = 5ms
- number of sampling points per oscillation = 100

- frequency = 2Hz
- cycle time = 200ms
- number of sampling points per oscillation = 2
