frequency amplitude

frequency amplitude amplitude 英语翻译Amplitude Modulation Amplitude modulation (AM) is a modulation technique in which the amplitude of a high frequency sine wave (usually at a radio frequency) is varied in direct proportion to that of a modulating signal.The modulating sign 英语翻译A filter with a tuning frequency more than 10% below the lowest harmonic frequency with considerable current/voltage amplitude.请相关人士帮助翻译以下这句话,filter:滤波器tuning frequency:调谐频率harmonic frequency:谐 frequency 求教关于三角函数的振幅、周期、频率这三种东西分别该怎么求?以函数p(t)=90+20sin(160πt）为例,求振幅（amplitude）、周期（period）、频率（frequency） 英语翻译是调幅频率吗?还是调幅波频率?还是甚么?原文是Does amplitude-modulated frequency have a role in the hypoalgesic response of interferential current on pressure pain sensitivity in healthy subjects? distance-amplitude-curves amplitude什么意思? diurnal amplitude是什么意思 amplitude modulation是什么意思 have an amplitude of amplitude modulation是什么意思 low amplitude oscillating VIDED FREQUENCY Frequency是什么意思 frequency是什么意思 frequency word
