FIGURE 1.1 The electromagnetic spectrum Electronics Handbook 4 some of the spectral regions are somewhat arbitrary Some spectral bands have no sharp edges and merge into each other, and some spectral sequences overlap each other slightly Optical Spectrum The optical spectrum is the middle frequency/wavelength region of the EM spectrum It is defined here as the visible and near-visible regions of the EM... Frequency Spectrum The RF range of the EM spectrum is the wavelength band suitable for utilization in radio communications extending from 10 kHz to 300 MHz (some authors consider the RF band as extending from 10 kHz to 300 GHz, with the microwave band as a subset of the RF band from 300 MHz to 300 GHz.) Some of the radio waves serve as the carriers of the low-frequency audio signals; other radio waves... H( j ω) denotes the angle of H(s ), with both quantities evaluated at s = yss (t ) A out j ω in the complex plane It is important to ret t ss alize that the steady-state output signal will be a scaled and time-shifted copy of the input −Aout signal, as depicted in Fig 1.3 The time tss denotes −A in the time at which the circuit is considered to be in the steady state The magnitude of the steady-state... subregions: (1) the optical spectrum, (2) the DC to light spectrum, and (3) the light to gamma ray spectrum The main subregions of the EM spectrum are now discussed, starting with the optical spectrum and continuing with the DC to light and the light to gamma ray spectrums Note that the boundaries between Copyright 2005 by Taylor & Francis Group Fundamental Electrical Theory VISION YGCB R O (0.78) 0.7 µm... m) (100 m down to 10 m) (10 m down to 1 m) (1 m down to 10 cm) (1 cm down to 1 cm) (1 cm down to 1 mm) The upper portion of the UHF band, the SHF band, and the lower part of the EHF band are further subdivided into the following bands Copyright 2005 by Taylor & Francis Group Fundamental Electrical Theory L band: 1 GHz up to 2 GHz S band: 2 GHz up to 4 GHz C band: 4 GHz up to 8 GHz X band: 8 GHz up to... Spectrum The microwave spectrum is the region of wavelengths lying between the far IR/submillimeter regions and the conventional RF region The boundaries of the microwave spectrum have not been definitely fixed, but it is commonly regarded as the region of the EM spectrum extending from about 1 mm to 1 m in wavelengths, that is, 300 GHz down to 300 MHz Copyright 2005 by Taylor & Francis Group Electronics Handbook. .. UV radiation from the sun causes tanning of the skin Radiation in the UV range can cause florescence in some substances, can produce photographic and ionizing effects, and is easily detected In UV astronomy, the emissions of celestial bodies in the wavelength band between 50 and 320 nm are detected and analyzed to study the heavens The hottest stars emit most of their radiation in the UV band DC to... represented in the frequency domain by the Bode u in + VC C − magnitude and phase responses of the circuit − [DeCarlo and Lin, 1995; Irwin 1995] For example, the capacitor voltage in the simple RC circuit shown in Fig 1.4 has the Bode magnitude |H( j ω)| FIGURE 1.4 Three series RC circuit and Bode phase response, θ( j ω) shown in Fig 1.5 The s -domain input-output transfer function H(s ) relating the output... input signal is the sinusoid v in (t) = Ain sin(ωt + φin ) for t ≥ 0, the steady-state output signal will be a sinusoid described by yss (t) = Aout sin(ωt + φout ) The magnitude and phase of the steady-state output signal are related to the magnitude and phase of the circuit’s input sinusoidal signal by Aout = Ain |H( j ω)| and φout = φin + angH( j ω) where |H( j ω)| denotes the magnitude of the complex-valued . alt="" The Electrical Engineering Handbook Series Series Editor Richard C.
