Great product. Have been using it for years. Not easy or intuitive to renew subscription. Ended up getting a 50% renewal but was initially offered a 75% renewal. Mainly use this for personal and light business use.

I like the ease of use. I do think the help system needs and upgrade. Should have a searchable index. It is hard to find topics. I am an experienced software guy and just want to find out how to do thinks.

Having to fill in Calendars for an upcoming Court Hearing and due to the limited space we can use to write its nice to be able to type the information in.

PDFfiller saved me significantly more than the cost of a subscription I found PDFfiller when searching for a (lease) document I needed to complete for a potential tenant. I signed up for the trial, and I will let it continue to a paid subscription. PDFfiller saved me significantly more than the cost of a one-year subscription. I'm really happy with the program, which allowed me to customize the document, and easily fill out the form.

Easy to use! Easy to upload files and edit them. Can add text, check boxes and even add wet signatures. All files kept in one place and can be easily downloaded back to my documents once edited!

Misunderstanding between monthly & annual plans I had to call twice because I did not understand the difference between the monthly and annual plan. Each time I called the person I talked to helped me with my misunderstanding. .

PDFfiller was an easy and convenient service to use. I filled out my PDF no problem and saved my documents. The customer support team was extremely helpful and accommodating when I needed to change my plan. Highly recommend!

It's great It's great. Not as good as adobe in the areas of text replacement or image addition. It is also not as sophisticated for selection mechanisms. If you need to fill in documents or create PDFs this is a solid application that can do the stuff that you will need quickly and cheaply.

The frequency resolution is equal to the sampling frequency divided by FFT size. For example, an FFT of size 256 of a signal sampled at 8000Hz will have a frequency resolution of 31.25Hz. If the signal is a sine wave of 110 Hz, the ideal FFT would show a sharp peak at 110Hz.
DFT Frequency Resolution. The frequency resolution is just the sample frequency divided by the number of samples (which is also the number of steps in the DFT sine table). This effect is typically called leakage, since energy appears to have leaked from the true frequency to many other frequencies.
The frequency resolution is the difference in frequency between each bin, and thus sets a limit on how precise the results can be. The frequency resolution is equal to the sampling frequency divided by FFT size. For example, an FFT of size 256 of a signal sampled at 8000Hz will have a frequency resolution of 31.25Hz.
The frequency resolution is defined as FS/N in FFT. Where FS is sample frequency, N is a number of data points used in the FFT. For example, if the sample frequency is 1000 Hz and the number of data points used by you in FFT is 1000. Then the frequency resolution is equal to 1000 Hz/1000 = 1 Hz.
A frequency bin is a segment [fl, fh] of the frequency axis that “collect” the amplitude, magnitude or energy from a small range of frequencies, often resulting from a Fourier analysis. The frequency bin can be derived for instance from the sampling frequency and the resolution of the Fourier transform.
Zero padding enables you to obtain more accurate amplitude estimates of resolvable signal components. On the other hand, zero padding does not improve the spectral (frequency) resolution of the DFT. The resolution is determined by the number of samples and the sample rate.
frequency bins are intervals between samples in frequency domain. For example, if your sample rate is 100 Hz and your FFT size is 100, then you have 100 points between [0 100) Hz. Therefore, you divide the entire 100 Hz range into 100 intervals, like 0-1 Hz, 1-2 Hz, and so on.
