Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .
In this type the derivative (slope) of the wave's amplitude (in sound waves the pressure, in electromagnetic waves, the current) is forced to zero at the boundary. So there is an amplitude maximum (antinode) at the boundary, the first node occurs a quarter wavelength from the end, and the other nodes are at half wavelength intervals from there:
The same amplitude F of the wave results from the same values of ξ C and ξ E, each of which may itself return to the same value over different but properly related choices of x and t. This invariance means that one can trace these waveforms in space to find the speed of a position of fixed amplitude as it propagates in time; for the argument ...
Illustration of the envelope (the slowly varying red curve) of an amplitude-modulated wave. The fast varying blue curve is the carrier wave, which is being modulated. The amplitude of a wave may be constant (in which case the wave is a c.w. or continuous wave), or may be modulated so as to vary with time and/or
The N400 amplitude seen to the target word (honey) will be reduced upon repetition due to semantic priming. [1] The amount of reduction in amplitude can be used to measure the degree of relatedness between the words. Another widely used experimental task used to study the N400 is sentence reading. In this kind of study, sentences are presented ...
Amplitude (a) vs. frequency (f) graph illustrating baseband bandwidth. Here the bandwidth equals the upper frequency. Here the bandwidth equals the upper frequency. Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies .
Baldoni hit back at the "false" claim saying, "During a creative meeting, which Lively requested to take place in her home, Baldoni read to her his notes from the intimacy coordinator, including a ...
In quantum mechanics, a probability amplitude is a complex number used for describing the behaviour of systems. The square of the modulus of this quantity represents a probability density . Probability amplitudes provide a relationship between the quantum state vector of a system and the results of observations of that system, a link was first ...
