The noise power spectrum is subtracted from the power spectrum of noisy speech to obtain an estimate of the power spectrum of the desired speech as follows:
The noise power spectrum is obtained by taking the average of the power spectrum of the noisy signal over several frames during silence period.
Generally speaking, the effects of the basic output frequency on the noise power spectrum of an oscillator can be mitigated using an impedance-matching method.
The ARIMA model noise power spectrum is close to 1/f, which characterizes the coloured noise, in particular the so-called flicker noise (Fig.
In addition, the breakdown voltage of the diode, the current I and the diode's cross-sectional area A all play an important role in determining the noise power spectrum of the IMPATT diode.
The flatness of the noise power spectrum is inversely proportional to the breakdown voltage [V.
Several diodes were used in this configuration and were tested for noise power spectrum flatness and the ENR value for an arbitrary DC current of 40 mA.
Figure 8 shows the noise power spectrum plot of the IMPATT diode with an ENR of 26 dB and [+ or -] 1 dB of flatness.
Also, the breakdown voltage of the diode, the current (I) and the diode's cross-sectional area (A), play an important role in determining the noise power spectrum of the IMPATT diode.
The second factor is the flatness of the noise power spectrum, which is inversely proportional to the breakdown voltage ([V.
Figure 6 shows the noise power spectrum plot of the SPD63 IMPATT diode with an ENR of 30 dB and [+ or -]1 dB of flatness in the frequency range of 26.
Figure 7 shows the noise power spectrum plot of the SPD49 IMPATT diode with an ENR of 26 dB and [+ or -]1 dB of flatness.
