The optical encoders give the operator continuous tuning of filters. NOISE REDUCTION The noise reduction functions of the DSP-599zx operate by examining a characteristic of signals and noise called correlation, and dynamically fil- tering out the undesired noise. The degree of correlation is relative. Ran- dom noise such as white noise or static is uncorrelated. Speech is moder- ately correlated. Pure tones such as heterodynes are highly correlated. The DSP-599zx measures correlation and automatically filters out noise that is outside its correlation threshold-holds. DATA and BANDPASS FILTERS Narrow band signals like CW an RTTY require bandpass filters with steep skirts and linear phase response. Linear phase response maximizes the unusable signaling rate for a given bandwidth and minimizes ringing often heard on other types of extremely sharp filters. Filter skirts are so steep that a signal literally falls off the edge of the passband as you tune through a signal. Bandwidths range from 10 Hz to 600 Hz, and center frequencies from 200 to 2150 Hz. Narrow filters are useful for trying to dig out ex- FIRST to simultaneously reduce noise, kill heterodynes and QRM!27 Empire Dr 27 Empire Drive, Suite 110 St. Paul, MN 55103 USA 651-489-5080 Voice 651-489-5066 Fax http://www.timewave.com E-mail: [email protected] DSP DSP DSP DSP DSP-599zx -599zx -599zx -599zx -599zx tremely weak signals from noise and QRM.

TEST INSTRUMENTS An added benefit of the powerful DSP processor and LCD display in the DSP-599zx is a Test Instrument mode. This mode is designed to provide the audio test instruments necessary for normal maintenance and setup of audio circuits in radio equipment installations. A low distortion audio sine wave generator and an audio millivoltmeter cover the frequency range from 20 Hz to 10 kHz. The millivoltmeter measures true rms and peak, as low as 1 mV, and the sine wave generator output is calibrated in the same units. The sine wave generator and the millivoltmeter operate simultaneously for gain and frequency response measurements. • NEW! Binaural CW NEW! Binaural CW NEW! Binaural CW NEW! Binaural CW NEW!
