The signals are modulated by a carrier frequency, and then combined into a ... WebMar 31, 2024 · differentiation amplifies high frequencies more than low frequencies; integration amplifies low frequencies more than high frequencies; That's pretty intuitive: high frequency means that the signal is changing quickly, hence the "rate of change" or "derivative" is big as well. The math around this is also simple and straight forward. cek plat motor jakarta
