normalized frequency การใช้

• There is a phononic band gap within a range of " normalized frequencies ".
• In digital signal processing, the angular frequency may be normalized by the sampling rate, yielding the normalized frequency.
• The use of normalized frequency allows us to present concepts that are universal to all sample rates in a way that is independent of sample rate.
• The resultant normalized frequency has units of " half-cycles / sample " or equivalently " cycles per 2 samples ".
• Formulas expressed in terms of \ textstyle f _ s and / or \ textstyle T are readily converted to normalized frequency by setting those parameters to 1.
• Comparison of the two series reveals that \ scriptstyle \ omega = 2 \ pi fT is a normalized frequency with units of " radians per sample ".
• Hence, there is a narrow range of normalized frequency 0.035 < ?a / ( 2?c ) < 0.04 where the bulk modulus and negative density are both negative.
• The normalized frequency " V " for this fiber should be less than the first zero of the Bessel function " J " 0 ( approximately 2.405 ).
• The monopolar resonance creates a negative bulk modulus above the normalized frequency at about 0.035 while the dipolar resonance creates a negative density above the normalized frequency at about 0.04.
• The monopolar resonance creates a negative bulk modulus above the normalized frequency at about 0.035 while the dipolar resonance creates a negative density above the normalized frequency at about 0.04.
• The following table shows examples of normalized frequencies for a 1 kHz signal, a sample rate \ textstyle f _ \ mathrm { s } = 44.1 kHz, and 3 different choices of normalized units.
• In general, when a sinusoid of frequency f \, is sampled with frequency f _ s, \, the resulting number of " cycles per sample " is f / f _ s ( known as normalized frequency ), and the samples are indistinguishable from those of another sinusoid ( called an " alias " ) whose normalized frequency differs from f / f _ s by any integer ( positive or negative ).
