What did Nasir Ahmed do?
Today, Nasir is perhaps best known for leading a group of researchers in the mid-1970s to develop what is called Discrete Cosine Transform (DCT), a technological technique that helped make image sharing and video-conferencing possible.

Who is Nasir Esther?
While it’s not unusual for the Dan Fogelman-created series to introduce new characters, the inclusion of Nasir Ahmed (Abhi Sinha) and his wife Esther Ahmed (Katie Sarife) is an unusual right-hand turn as the real-life couple’s love story is briefly featured without any overt connection to the Pearsons.

What is FFT in MFCC?
2.4 Fast Fourier Transform-It is a signal analysis technique which is used to extract and compress some features of the speech signal without losing any relevant information so that speech processing becomes easier. It represents the given signal in a frequency domain.
What is frame blocking in MFCC?
The MFCC processor which is less susceptible to variations is chosen to mimic the behavior of the human ears. 2) Frame Blocking In this stage the continuous speech signal is divided into block frames of N samples, with adjacent frames being separated by M ( M < N ). The first frame consists of the first N samples.
What is DCT and DFT?
DFT is the discrete version of the Fourier Transform (implementable in a computer). DCT is the discrete cosine transform, that is, the DFT when taking only the real part. FFT is not a theoretical transform: it is just a fast algorithm to implement the transforms when N=2^k.
