Frequency multiplication

Frequency multiplication is a process where an electronic circuit increases the frequency of an input signal, producing an output at a multiple of the original frequency. For example, if you input a 10 MHz signal and use a frequency multiplier, the output might be 20 MHz (double), 30 MHz (triple), or higher, depending on the device. This technique is essential in applications like communications and radar, where higher frequencies improve performance. It works by generating new signals at harmonic frequencies (multiples of the original), often through nonlinear electronic components like mixers or specialized circuits called frequency multipliers.
