试题来源: 解析 B。解析:amplitude是振幅,它表示的是波的振动幅度。frequency是频率,它表示的是单位时间内完成周期性变化的次数,也就是每秒内波的完整周期数。所以这里代表每秒波的完整周期数的是frequency,A选项amplitude不符合,C选项both错误,D选项neither不对。反馈 收藏 ...
Regardless of the type of wave or the medium through which it travels, all waves can be described and measured using the following characteristics: amplitude, frequency, wavelength, speed, and period. To start - what is the frequency of a wave?View...
The next component in the signal path is the input filter. Spectrum analyzers use a fixedlow-pass filterin the low band and a tunable bandpass filter called a preselector (we will discuss the preselector in more detail in Chapter 7) in the higher frequency bands. The low-pass filter has...
