17.Usually the bridge circuit has a relatively high input impedance so that it has an insignificant effect on the signals in the transmission line.通常桥接电路具有较高的输入阻抗,因此传送线上的信号将不受影响。 18.In this article by applying the output equivalent circuit, a formula of input impe...
Currently I have the following formula to come up with the proper rounding to 1330 which puts a priority of rounding to the smaller whole number of 190, but it could easily be switched to prioritze 500 first: =IF((ABS(MROUND(D31*$F$18,190)-(D31*$F$18))/(D...
Example: Image 1. The power factor (cosθ) of the drive is higher than that of the motor (0.95 > 0.88). Through the calculation using the three-phase real power formula, the input current of the drive is smaller than the input current of the motor (24.74 A < 30.51 A).Back...
This paper used massive inputs, including rotor angle, speed and power of generators, and formed a series of mathematical formulae using these parameters for prediction of stability. At last, by using the confidence level of ensemble classifiers (C5.0 DT, ELM, Boosting C5.0, and RF), layers...
This gain is basically a measure of the amplification factor/power gain which is expressed in decibels. The power gain is expressed as: Power gain=10×log(PoutPin) dB Pout and Pin are provided in the question hence we can easily calculate the gain in d...
Maximum junction temperature is calculated from the ambient temperature and power dissipation using the formula: TJ = TA + PD ×θJA. ADP1850 Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional ...
Therefore, it makes sense that in a receiver system, the first amplifier is a low noise amplifier with large power gain. In general, for an arbitrary number of blocks, the total noise factor can be found according to the Friis noise formula as (3.30)Fcascade=F1+F2−1G1+F3−1G1G2+...
The value of the 10-bit word (ISCALE) sets IFS according to the following formula: IFS = 120 μA × 72 + 3 16 ISCALE (6) TUNING WORD PROCESSING The frequency tuning words that dictate the output frequency of the DDS come from one of three sources (see Figure 46). ► The free ...
