a further signal is derived having a frequency equal to that of the input divided by n, which signal is applied to a counter 4 having a controllable counting period, and an oscillator 8 is caused to develop an output signal of which the frequency of the nth harmonic differs from the input...
The absorption frequency of a fundamental absorption band in the IR is the same as the frequency of the molecular vibration that caused the absorption. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 About this pageAdd to MendeleySet alert Discover other topics ...
ONE of the common characteristics of all nonlinear electrical devices, such as vacuum tub s, is the generation of harmonic frequencies in which, with a pure sine wave input, the output contains a series of multiples of the input frequency. For more than a decade, piezo-electric oscillators ...
The hypothesis behind this analysis is that the fundamental frequency can be obtained by measuring the higher harmonic frequency components. The Fourier transformed signal shows a number of regularly spaced peaks of fundamental period of the segment that corresponds to harmonic spectrum of the signal. ...
We adapt the Quantum Monte Carlo method to the cascaded formalism of quantum optics, allowing us to simulate the emission of photons of known energy. Statistical processing of the photon clicks thus collected agrees with the theory of frequency-resolved
A direct frequency synthesizer is provided with a single stage or multiple cascaded stages. Each stage includes a fixed frequency input channel and a selectable frequency input channel which are coupled respectively to the I and L ports of a mixer. The i

For the amplitude and phase of the nth harmonic of the output signal, we thus have the following: (3.79)yn=xnHnT0⇔yn=xnHnT0∡yn=∡xn+∡HnT0 Example 3.47 Consider an LTI system whose frequency response is as follows: Hf=-jπ4sgnf Suppose the input signal x(t) is an odd ...
Ergler et al.14 successfully observed the vibrational motion by using a pair of intense sub-10-fs pulses of a Ti:sapphire laser as the pump and probe pulses. Kelkensberg et al.16 demonstrated that an isolated attosecond pulse generated as a high-harmonic field of an a-few-cycle time ...
