If cells are the building blocks of life, transistors are the building blocks of the digital revolution. Without transistors, the technological wonders you use every day --cell phones,computers, cars -- would be vastly different, if they existed at all. Before transistors, product engineers used...
The voltage-control viewpoint shown by the Ebers-Moll explanation does appear widely in textbooks, but it certainly isn't widely learned. If it had been learned, then people wouldn't get angry when they hear that transistors are voltage-controlled; that the collector current is proportional to...
If a chain of transistors conducts current, it has the value of 1. If it doesn't conduct current, it's 0. At first, all transistors are set to 1. But when a save operation begins, current is blocked to some transistors, turning them to 0. This occurs because of how transistors are...
By creating a sine wave and running it through a wire, you create a simple radio transmitter. It is extremely easy to create a sine wave with just a few electronic components — acapacitorand aninductorcan create the sine wave, and a couple of transistors can amplify the wave into a powe...
transistors can amplify signals because of their ability to control a larger current with a smaller input current or voltage. in an amplification process, a small input signal applied to the base of a transistor causes a much larger current to flow through the collector, resulting in an ...
Before comparing the print to stored data, the scanner processor makes sure the CCD has captured a clear image. It checks the average pixel darkness, or the overall values in a small sample, and rejects the scan if the overall image is too dark or too light. If the image is rejected, ...
Why transistors are important A transistor has only one circuit element. In small quantities, transistors are used to create simple electronic switches. They're the basic elements in integrated circuits (ICs), which consist of a large number of transistors interconnected with circuitry and baked into...
Once transistors were perfected (transistors were invented in 1947), computers started using gates made from discrete transistors. Transistors had many advantages: high reliability, low power consumption and small size compared to tubes or relays. These transistors were discrete devices, meaning that ...
When remote buttons are pressed, signals are generated in the form of electrical pulses that travel through the air. How do I increase the range of my RC transmitter? To increase the range, you can use transistors to strengthen your RC transmitter’s signals. However, this might be...
A small metal stake or pipe that you can drive into the ground (or, if the transmitter has a guard rail or metal fence nearby, you can use that). A crystal earphone: This simple precursor to earbuds connects directly to the antenna diode. To make the process easier, some kits are also...
