If a wave of velocity v, frequency f and wavelength [itex]\lambda[/itex] travels through a medium whose density is inversely proportional to distance, such that the further the wave travels the greater the velocity of wave, in what manner do f and [itex]\lambda[/i...
Now let’s measure the period—the time it takes to complete a full wave cycle. How long did it take your rope wave to complete a cycle? If the frequency was two cycles in one second, the time of one cycle was half a second. You can confirm this with mathematical equations. ...
The resulting system does not perfectly exhibit the desired ideal temporal tuning, but still the overall system correctly exhibits the desired time cells. The accuracy of the match between the desired temporal tuning and the actual temporal tuning generally increases with the number of neurons. ...
First, the consistency threshold was raised from 0.8 to 0.85 for case rescreening, and configuration results did not change significantly. Secondly, this study further increased the case frequency threshold and performed further censoring of cases by raising the threshold from 8 to 9, and the ...
the change in frequency of light or sound emitted by a moving object that in the astronomical world manifests as the so-calledredshift, the shift towards "redder", longer wavelengths in objects speeding away from us. In a leap of intuition, Rømer determined that light was taking measurable...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
Frequency response can be considered a filter, which can boost or attenuate the input signal to alter the sound. In other words, an ideal frequency response does not change the relative levels of the bass, middle, or treble from the source. By comparison, if you’ve messed around with any...
So, beyond noise and a bit of extra heat in the controller from switching faster, what changes when you change PWM frequency? A higher PMW frequency will reduce the ripple current in the motor, which should improve efficiency a little bit especially if your mo...
Let's say that you are trying to build a radio tower for radio station 680 AM. It is transmitting a sine wave with a frequency of 680,000 hertz. In one cycle of the sine wave, the transmitter is going to move electrons in the antenna in one direction, switch and pull them back, ...
When using 4030 Ripple/Noise meter to measure noise, picking different frequency bandwidth will cause its value to change. Normally, high frequency bandwidth(20Hz~50MHz) will result in higher value than using low frequency bandwidth. Figure 8 typical power supply output noise Figure 9 Typical ...
