Amplitude and Frequency/Phase Modulation
I always had difficulties in understanding frequency modulation (FM) and its frequency spectrum. Even for the pure tone modulation, the FM spectrum consists of an infinite number of sidebands whose signs change from one sideband to the next one and whose amplitudes are given by the horrible Bessel functions. . . I work for Zurich Instruments, a Swiss maker of lock-in amplifiers and it has becom...
متن کاملDetection of combined frequency and amplitude modulation.
This article is concerned with the detection of mixed modulation (MM), i.e., simultaneously occurring amplitude modulation (AM) and frequency modulation (FM). In experiment 1, an adaptive two-alternative forced-choice task was used to determine thresholds for detecting AM alone. Then, thresholds for detecting FM were determined for stimuli which had a fixed amount of AM in the signal interval o...

متن کاملAmplitude and frequency modulation control of sound production in a mechanical model of the avian syrinx.
Birdsong has developed into one of the important models for motor control of learned behaviour and shows many parallels with speech acquisition in humans. However, there are several experimental limitations to studying the vocal organ - the syrinx - in vivo. The multidisciplinary approach of combining experimental data and mathematical modelling has greatly improved the understanding of neural ...
متن کاملMechanical frequency and amplitude modulation of a quantum cascade laser integrated with a plasmonic nanoantenna.
Surface plasmons (SPs) can be generated at the interface between two materials having opposite signs of dielectric susceptibility. [ 1 ] This principle has recently been exploited in many applications, ranging from enhanced optical transmission (EOT), [ 2 ] which can be used for enhanced photodetection, [ 3 ] biosensing, [ 4 ] optical trapping of small particles [ 5 ] and bacteria, [ 6 ] and ev...
