چکیده

The phenomenon of vibrational resonance (VR) in the classical Morse oscillator influenced by narrow band and wide band, frequency modulated signals is numerically studied. Vibrational resonance was found to occur when the amplitudes f and g and frequencies ω and Ω of the signals were varied. The dynamics of the system is studied in the presence of both signals separately. Vibrational resonance and dynamics of the system were characterized using the response amplitude and bifurcation diagram. Key word: Vibrational resonance, Classical Morse oscillator, Narrow-band frequency modulated signal, Wideband frequency modulated signal, Response amplitude.

A Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band

A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...

Spontaneous Emission Spectrum from a Driven Three-Level Atom in a Double-Band Photonic Crystal

Abstract The spontaneous emission spectrum from a driven three-level atom placed inside a double-band photonic crystal has been investigated. We use the model which assumes the upper levels of the atomic transition are coupled via a classical driving field. The transition from one of the upper levels to lower level couples to the modes of the modified reservoir, and the transition from the oth...

Adaptive heterodyne filters (AHF) for detection and attenuation of narrow band signals

A fixed filter may be converted into an adaptive filter with a single adaptation parameter through the use of a new Adaptive Heterodyne Filter (AHF) concept in which the frequency of the heterodyne signal is adjusted thereby translating the entire filter transfer function in frequency. If the fixed filter is selected to be a very narrow-band band-pass filter, the new AHF concept can be used ver...
