Types of Oscilloscopes Several types of oscilloscopes are available, both analog and digital, for a range of prices. Since digital oscilloscopes can miss some transient signals, analog oscilloscopes are still prized for transient troubleshooting applications. However, high-end digital phosphor oscilloscopes can provide similar capabilities. Analog Oscilloscopes An analog oscilloscope displays the signal picked up by a probe and traces it on the screen. Storage capabilities allow the waveform to display for extended periods of time rather than decay immediately....

Understanding Camera Specs A handful of common technical values influence ideal shooting patterns. Effective PIxels The number of effective pixels determines the resolution of your camera. (A megapixel is equal to a million pixels.) Cameras with more megapixels create larger prints than those with fewer megapixels, assuming the exposure and focus are good. So, if your camera isn’t creating sharp, large prints, check the number of effective pixels it has. Beyond still image resolution, you should see resolution provided for video recording options within the camera’s specification list....

How Audio Speakers Use High-Pass Filters A high-pass filter is used in an audio system to allow high frequencies to get through while filtering or cutting low frequencies. A high-pass filter is used with small speakers to remove bass, for example. In many cases, these filters are built into the speaker, but in some more elaborate do-it-yourself speaker setups, a high-pass filter unit can be wired to the system. How High-Pass Filters Work With Microphones Some brands of microphones include a selectable filter....

Whether it uses a laser or ball, or the mouse is wired or wireless, a movement detected from the mouse sends instructions to the computer to move the cursor on the screen in order to interact with files, windows, and other software elements.
