Signal to Noise Ratio
Measured with respect to a recording level of 1,040 nWb/mat 15 and 7.5 ips,
and 740 nWb/m at 3.75 ips, using AMPEX 456 or equivalent tape.
Unwtd: Using a 30Hz to 18kHz RC filter to eliminate noise outside the audio
spectrum.
Wtd: Using a NAB or ANSI "A" weighting filter and a 1kHz reference.
