why use high frequency

The main advantage of high frequency signals is that the signal may be transmitted over very long distances and thus dissipates very less power. The antenna height required for transmission is reduced at higher frequencies. Thus, the audio signals must be sent with the high frequency carrier signals for communication purpose

5g spectrum and frequencies: everything you need to know

Dec 13, 2020 · One part of the radio spectrum has a high frequency range between 30 GHz and 300 GHz (part of the EHF band), and is often called the millimeter band (because its wavelengths range from 1-10 mm). Wavelengths in and around this band are therefore called millimeter waves (mmWaves). mmWaves are a popular choice for 5G but also has application in areas like radio astronomy, …

thebenefits of an intermediate frequency in rf systems

thebenefits of an intermediate frequency in rf systems

If an IF receiver must include high-frequency circuitry for performing the frequency translation from RF to IF, why not simply use the baseband frequency instead of an intermediate frequency? A receiver that shifts the signal down to the baseband instead of the IF is referred to as a direct-conversion (or homodyne, or zero-IF) architecture

High Frequency - The high frequency mode will initiate and maintain the arc during the zero crossing of the A.C. sine wave. Three positions exist on most GTAW machines: 1) Start - This mode helps arc initiation without making actual contact to the work with the electrode. The “Start” mode is most often used in D.C. welding

The high frequency machine connects to a glass probe (by a wire). That glass probe is filled with a gas, such as argon or neon. The gas makes the probe glow a certain color when it’s turned on (e.g. violet, orange, red). Probes come in different shapes to accommodate different areas of the face. The most common one is called the mushroom probe
