Spectrum plot of an DSB-SC signal:

Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts.

Spectrum analysis can be performed on the entire signal.

Spectrum of a bandlimited signal as a function of frequency.

Unlike the Spectrum however, one of the blacks is actually " transparent ", so the MSX video picture could be overlayed on another video signal, for example one from a video disk.

Spectrum of a DVB-T signal in 8k mode ( note the flat-top characteristics ).

Spectrum analyzer types are dictated by the methods used to obtain the spectrum of a signal.

Spectrum analysis can be used at audio frequencies to analyse the harmonics of an audio signal.

Spectrum of an FM broadcast signal.

Digital Spread Spectrum ( DSS ) variants spread their signal over a range of frequencies providing more resistance to signal fade. This technology enabled the digital information to spread in pieces over several frequencies between the receiver and the base, thereby making it almost impossible to eavesdrop on the cordless conversation.

Digital Spread Spectrum ( DSS ) typically uses frequency hopping to spread the audio signal ( with a 3 kHz bandwidth ) over a much wider range of frequencies in a pseudorandom way.

With hindsight, the machine lacked the RAM ( a typical program would need to fit in only around 20 kB once display memory is subtracted ) and processing power to take on the prevailing Sinclair ZX Spectrum and Commodore 64.

Timex of Portugal sold 2 versions of TC2068: the Silver TC2068 version came with a ZX Spectrum emulator cartridge and a black TC2068 version sold with TimeWord word processing cartridge plus the Timex RS232 Interface to use TimeWord with a RS232 printer.

Hewson weren't happy to see their most successful development partner jump ship, particularly because Graftgold were due to deliver two keenly anticipated titles -- Magnetron ( by Steve Turner, for the ZX Spectrum ) and Morpheus ( by Andrew Braybrook, for the C64 ).

Firebird's success allowed them to acquire a number of third party developers ( see Telecomsoft acquisitions below ) and they also established a deal with Ultimate Play The Game, whereby they would convert and publish a number of their successful ZX Spectrum games to the Commodore 64.

What differentiated PRISM from other services – some of which included ON-TV, SelecTV, and Z Channel – is that it broadcast exclusive and extensive sports coverage, which included Flyers, Philadelphia Phillies, and Philadelphia 76ers games, Big 5 basketball, and live World Wrestling Federation events held at The Spectrum ( the venue itself lending to the station's tongue-in-cheek naming as viewing a " prism " allowed one to see " the spectrum ").

Spectrum continuation analysis ( SCA ) is a generalization of the concept of Fourier series to non-periodic functions of which only a fragment has been sampled in the time domain.
