» subplot(2,2,3),plot(f,db(Sx1)); %plot of PSD of x1 » subplot(2,2,4),plot(f,db(Sx2)); %plot of PSD of x2. The PSD for each signal looks more or less flat across the frequency band. This type of noise is referred to as white, and if we had taken an infinitesimally small time increment, we would see this flatness across the entire frequency band.

The transistor Q4 and Q5 form an active load current mirror circuit. The base voltage of Q1 is the voltage VB across zener DB . Then, VB = (VBE * n) +VBE across Q1 + VBE across Q2 + drop across R2 .Here, n is the number of diodes. It can be expressed as . Differentiating for VB , I0 , R2 and VBE partially, with respect to temperature T, we get

Pfinal = Pref x 10(dB/10) or Vfinal = Vref x 10(dB/20) Pref = Pfinal x 10-(dB/10) or Vref = Vfinal x 10-(dB/20) IV. 5 Volts are sent on a cable, but the voltage measured at. the end is 10 Volts. What is the gain or loss in decibels? V. If 5 Volts are sent, and the maximum amount of loss can. be no greater than 5 dB, what is the minimum allowable

The voltage or current gain of an amplifier expressed in dB is 20 log10|G|, where G = Vout/Vin for voltage gain or Iout/Iin for current gain.. The frequency response of an op-amp has a low-pass characteristic (passing low-frequency signals, attenuating high-frequency signals), Figure 10.

where is the signal-plus-noise voltage evaluated at a specific time and is the noise voltage evaluated at a specific time. This carries some subtle implications. First, when one finds detection probability it is tacitly assumed that the target return is present at the time the output of the threshold device is checked.
