## How do you calculate fMAX?

If the number of teeth in the gear are known, the formula is 3.25 times the teeth number, multiplied by the RPM. An example of this would be if the number of teeth was 17, and the RPM was 1750, F-MAX would be 97,000x.

### How is hartleys fMAX calculated?

Hartley’s Fmax Table. Degrees of freedom: Subtract 1 from your sample size to find the degrees of freedom. For example, if you have 10 items in your sample, then df = 10 – 1 = 9. k: is the number of levels/groups or conditions.

#### What does fMAX mean?

The maximum clock frequency that can be achieved without violating internal setup (tSU) and hold (tH) time requirements. Unrestricted fMAX is the maximum frequency at which a design can run.

**What is transistor Fmax?**

Fmax is the frequency where unilateral gain (U) becomes unity, or zero dB. It is still one of the most important figures of merit for a transistor, especially at microwave frequencies. Below, we have plotted “U” versus frequency for an imaginary transistor with Fmax=400 GHz.

**What is Hartley’s F max?**

In statistics, Hartley’s test, also known as the Fmax test or Hartley’s Fmax, is used in the analysis of variance to verify that different groups have a similar variance, an assumption needed for other statistical tests. It was developed by H. O. Hartley, who published it in 1950.

## What is Levene’s test for equality of variance used for?

Levene’s test ( Levene 1960) is used to test if k samples have equal variances. Equal variances across samples is called homogeneity of variance. Some statistical tests, for example the analysis of variance, assume that variances are equal across groups or samples. The Levene test can be used to verify that assumption.

### What is the difference between fT and Fmax?

fT is defined as the transition frequency which small-signal current gain drops to unity. fmax is the frequency at which the unilateral power gain becoms unity.

#### What is unilateral power gain?

A unilateral device is one whose scattering parameter. . This implies that the transistor network has no internal feedback. This requirement is very difficult to achieve at microwave frequency.

**How is line of resolution calculated?**

LINES OF RESOLUTION Each line will cover a range of frequencies, and the resolution of each line can be calculated simply by dividing the overall frequency (Fmax) by the number of lines. For example, an Fmax of 120,000 CPM and 400 lines gives a resolution of 300 CPM per line.

**When to use multiple regression analysis in SPSS?**

Multiple Regression Analysis using SPSS Statistics. Introduction. Multiple regression is an extension of simple linear regression. It is used when we want to predict the value of a variable based on the value of two or more other variables.

## How do I perform multiple linear regression on exam data?

Step 1: Enter the data. Enter the following data for the number of hours studied, prep exams taken, and exam score received for 20 students: Step 2: Perform multiple linear regression. Drag the variable score into the box labelled Dependent. Drag the variables hours and prep_exams into the box labelled Independent (s). Then click OK.

### What is multiple regression in statistics?

Multiple regression is an extension of simple linear regression. It is used when we want to predict the value of a variable based on the value of two or more other variables.

#### Does SPSS include a confidence interval for R-square?

Sadly, SPSS doesn’t include a confidence interval for R 2 adj. However, the p-value found in the ANOVA table applies to R and R-square (the rest of this table is pretty useless). It evaluates the null hypothesis that our entire regression model has a population R of zero.
