Abstract: In modern pulsed Doppler radars, the use of staggered pulse repetition frequencies (PRFs) as inputs for the Chinese Remainder Theorem (CRT) is a common practice to solve Doppler frequency ...

Use Pythagoras’ theorem to show a triangle is right-angled or to find one side of a right-angled triangle when two sides are known. Make sure you are confident at substituting into and manipulating ...

Sometimes it is not possible to divide one number by another exactly. Anything left over that cannot be divided exactly is called the remainder. When you are solving problems and there is a remainder, ...

Abstract: The sampling theorem is one of the most basic and fascinating topics in engineering sciences. The most well-known form is Shannon's uniform-sampling theorem for bandlimited signals.
