Simplified analysis of the readout waveform for an elliptical mark
Abstract:
A simplified equation for the readout waveform from an elliptical mark is analytically derived and confirmed. This approach approximates the elliptical mark by using an equivalent mark with the width of a δ function and an equivalent readout beam spot. The equation is verified by comparison with precise numerical calculations. Good agreement is obtained with the practical dimensions of optical recording. The equation determines the characteristics of the readout waveform in terms of the dimensions of the elliptical mark.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
