Active-Amplifier-Array Diagnostics Using High
... IF that is fed into an RF lock-in amplifier [11], [12]. Using phase-locked-loop electronics in the stabilized laser system, one is able to synchronize the continuous-wave (CW) signal from a microwave synthesizer to the laser pulse train, with the small offset frequency (i.e., the IF) providing the t ...

Square-wave excitation of a linear oscillator
... In this equation ω0 is the natural frequency of oscillations of charge in the circuit in the absence of resistance. It depends√on the capacitance C of the capacitor and the inductance L of the coil: ω0 = 1/ LC. The damping constant γ = R/(2L) characterizes the dissipation of electromagnetic energy o ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
