Abstract
A method and apparatus of correcting a data signal sampled at a first rate to a data signal displayed on a video monitor at a second rate is claimed. A data signal is received at a first rate. The data signal is separated into data windows. The minimum and maximum values and positions of data points in data windows are identified relative to a reference, and displayed on a video monitor.
Claims8
A method for sampling and displaying a data signal, the method comprising:
- receiving a first data signal sampled at a first rate;
- sampling the first data signal at a second rate to generate a second data signal having a first data point and a second data point;
- calculating a first time off-set from a reference point for the first data point;
- calculating a second time off-set from a reference point for the second data point;
- displaying the first data point according to the first time off-set;
- and
- displaying the second data point according to the second time off-set.
