Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...

Oscillators may use crystals as precise tuned circuits. If you have a vector network analyzer (VNA) — or even some basic test equipment — you can use it to learn the parameters of a crystal. [All ...

The circuit was designed to create a frequency convert with the use of a crystal oscillator for the conversion of 10 MHz to 1 MHz. 7404 – a hex inverter utilizing TTL to achieve high speed at nominal ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...

Historically when hams built low power (QRP) transmitters, they’d use a crystal to set the frequency. Years ago, it was common to find crystals in all sorts of radios, including scanners and handheld ...

Just as most electronic products today contain at least one embedded controller, most also have at least one crystal oscillator. In fact, some multiprotocol networking and telecom equipment can ...

A newly demonstrated link between a time crystal and a mechanical system opens a door scientists once thought closed.

A plasma-containing crystal, tunable by varying a voltage, could increase the bandwidth of high-speed communication networks and generally enhance high-speed electronics. Gems are known for the beauty ...
