摘要： A protection panel is provided that enhances the color quality and/or contrast of a rear projection television set. The protection panel has a spectral transmittance that peaks at dominant wavelengths of red, green, and blue light, and that is reduced at wavelengths between red and green light and between green and blue light. The spectral transmittance at the dominant wavelengths is between sixty and eighty percent. Preferably, the spectral transmittance at the wavelengths between red and green light and between green and blue light are at least five percent less than at the dominant wavelengths. In addition, the spectral transmittance at a dominant wavelength of red light is about five percent less than at a dominant wavelength of blue light to reduce blue color saturation.

摘要： A local carrier wave output from a synthesizer to quadrature demodulators is multiplied by an offset that makes a frequency shift by an integer number of subcarriers in units of sub-carrier bands. The offset is set to a value obtained by multiplying the number sequentially counted up from 0 to the number of unused sub-carriers included in guard tones in a signal band by the bandwidth of a sub-carrier. By shifting the frequency of the local carrier wave at the time of quadrature demodulation with the offset, the SNR of a baseband signal is prevented from being constantly degraded by a frequency characteristic possessed by the circuit of a receiver in a particular sub-carrier signal. Especially, by preventing a pilot signal from being constantly degraded, the signal can be received with higher accuracy.
