We report an all-optical radio-frequency (RF) spectrum analyzer with a bandwidth greater than 5 THz, based on 50 cm long spiral waveguide in CMOS-compatible high-index doped silica platform. By carefully mapping out the dispersion profile of waveguides for different thicknesses, we identify optimal design to achieve near-zero C-band. To demonstrate capability RF analyzer, measure optical output...

Determining the noise parameters of twoports requires measurement of spectral noise-power density. Normally such measurements are carried out with highly sensitive receivers by the radiometer principle or with commercial, automatic noise-factor meters. Lately spectrum analyzers too come equipped for this application, although they are mainly intended for observing spectra with discrete frequenc...

This paper presents an experimental method to perform tests on compact fluorescent lamps operated with distorted voltage waveform conditions. The voltages used for the tests are obtained from an arbitrary waveform generator. It consists of a computer, a multifunction card and the software package. The characteristics of the voltage are entered from the computer that loads the required waveform ...

In this paper, The difference between getting the output spectrum directly using spectrum analyzer and obtaining the spectrum digitally in measuring clock jitter effect on continuous-time Σ∆ modulator is analyzed. It is shown that clock jitter can be seen as input-referred or output-referred, depending on the nature of the measurement tool. Quantization noise and jitter noise are analyzed and c...

Approximately two years ago I authored a paper entitled, “The Forensic Examination of Video Recordings” which discussed some of the more conventional forensic techniques for examining questioned analog videotapes regarding their originality and for possible evidence of tape alteration. This paper specifically addressed the various mechanical and electrical signal anomalies that occur when editi...

The current high usage of frequency-equalized sound systems in the commercial sound and recording fields places increasing demands on the user-operator of the system to ensure that the overall system holds its designed value of spectral flatness during normal day-to-day operation. An inexpensive generator of pseudo random pink noise with adequate spectral purity is described which can be used a...

In mobility management, detection of spectrum hole plays very important role for doing spectrum handoff mechanism. Operation of the cognitive radio depends on the spectrum sensing which is the most important task in case of cognitive radio network. Detection of spectrum holes (underutilized sub-bands of the radio spectrum) estimates average power, throughput and utilized time for each spectrum ...
