By generating the color information at exactly the right color subcarrier frequency (approximately 3.58 MHz) it is possible to produce color frequency components sandwiched in between the
Frequency components of the black and white video signal. This technique is known as:

Question

Quizplus · Accepted Answer

Interleaving is the technique used to describe the process of inserting color information between the frequency components of the black and white video signal, effectively allowing both color and black and white images to be transmitted within the same signal without interference. This is achieved by carefully choosing the color subcarrier frequency (around 3.58 MHz in NTSC systems) to fit within the existing spectrum allocated for the video signal.
