What is scaling in FFT?

The Fast Fourier Transform Product guide (PG109) explains that scaling is used to avoid bit growth in the output as a result of the arithmetic operations used to implement the FFT algorithm.

What is the time scaling property of Fourier transform?

Time Scaling

If a function is expanded in time by a quantity a, the Fourier Transform is compressed in frequency by the same amount.

What is 64 point FFT?

The 64-point FFT is realized by decomposing it into a two-dimensional structure of 8-point FFTs. This approach reduces the number of required complex multiplications compared to the conventional radix-2 64-point FFT algorithm. The complex multiplication operations are realized using shift-and-add operations.

How many periods do I need for FFT?

Number of periods of signal required when doing an FFT: 1

yup.
