Real-time Waveform Analysis

The Mathematics of Induction

1. The Universal EMF Equation

The Root Mean Square (RMS) voltage induced in a transformer winding is determined by the frequency, turns, and maximum magnetic flux.

E = 4.44 ⋅ f ⋅ N ⋅ Ī¦m
Where f is frequency, N is number of turns, and Ī¦m is peak magnetic flux in Webers.

2. Magnetic Flux Density (B)

This calculates how "crowded" the magnetic field lines are in the core. If B exceeds 1.4 - 1.6 Tesla, the iron core saturates.

B = Ī¦m / A
Where A is the cross-sectional area of the core in m².

3. Transformation Ratio (k)

The relationship between primary and secondary voltage is directly proportional to the number of wire wraps (turns).

Vs / Vp = Ns / Np = k
If k > 1, it is a Step-Up transformer. If k < 1, it is Step-Down.

4. Faraday's Law (Instantaneous)

The oscilloscope shows the phase shift because induced voltage is the negative rate of change of magnetic flux.

e(t) = -N (dĪ¦ / dt)
This explains why the Flux waveform lags the Voltage waveform by 90°.

Core Process of GMSK Modulation Phase Accumulation (Integration of Filtered Signal) After applying Gaussian filtering to the Non-Return-to-Zero (NRZ) signal, we integrate the smoothed signal to produce a continuous phase signal. For GMSK, the modulation index is $h=0.5$, meaning a bit '1' results in a phase shift of $\pi/2$: Īø(t) = 2Ļ€h ∫ 0 t m filtered (Ļ„) dĻ„ This integration is crucial for avoiding abrupt phase transitions, ensuring smooth and continuous phase changes.
