    • Rainfade


      Rainfade refers to a phenomenon that occurs during strong rain or snowfall in which satellite signals are prevented from reaching their destination. Rainfade may also refer to extensive cloud cover, strong winds, or any other environmental effect that distorts a satellite broadcast, but is most often observed during rainfall. Rainfade may also refer to the

      How to Install a Car Audio System

      Those on a tight budget and would like to save possibly hundreds of dollars on installation costs and those who would like to customize their car audio system may want to install the car audio system themselves. Whatever the reason, it is quite easy to install a car audio system and here are some tips.

    • Hz (Hertz)

      Hz (Hertz)

      Hertz is the International System of Units (SI) base unit of measurement for frequency. Hz is the standard abbreviation for hertz. One hertz is defined as “one complete cycle per second,” and can be applied to any periodic event, but is usually applied to sound waves, electrical current, and radio waves. The hertz is the

    • Inductor


      An inductor is a conducting coil, wrapped around a core, that creates inductance when an alternating current flows through it. Inductors are used to impede the flow of current in a circuit. The conductor is usually thin magnet wire, and the core is usually air or steel. Working of an Inductor When the alternating current

    • Crosstalk


      Crosstalk is a form of interference caused by signals in nearby conductors. The most common example is hearing an unwanted conversation on the telephone. Crosstalk can also occur in radios, televisions, networking equipment, and even electric guitars. Causes of Crosstalk Crosstalk is caused by coupling, the transfer of electrical energy between conductors. The three main

    • Trickle Charging

      Trickle Charging

      Trickle charging, also called float charging, is the replacement of charge lost through self-discharge. Trickle chargers work at a lower rate than quick chargers, and are used to keep a battery at full charge, not to charge it from empty. Some battery chargers use electronics to control both quick and trickle charge modes, allowing them

    • Breadboard


      A breadboard is a thin rectangular piece of insulating material used to hold electronic components when making circuit prototypes. They have many rows and columns of conductive points for inserting component terminals and jumper wires. The original breadboards were just wooden boards, presumably used to cut bread on, but the modern versions have plastic cases

    • Internet Repeater

      Internet Repeater

      An Internet repeater is a device that allows amateur radio operators to communicate with each other over the Internet, much like how VoIP software allows telephone operators to communicate with each other over the Internet. Internet repeaters should not be confused with wireless repeaters, which allow users to extend the range of a wireless network.

    • Solid State Relays

      Solid State Relays

      A solid state relay is a device that controls voltage to allow or prevent a voltage or current from passing through a circuit without using any moving parts. Solid state relays are commonly found in control systems that use large amounts of power and must be switched on and off on a regular basis. Solid

    • GMSK (Gaussian Minimum Shift Keying)

      GMSK (Gaussian Minimum Shift Keying)

      MSK (Minimum Shift Keying) is a type of continuous frequency shift modulation that is used to transfer radio signals from satellites and radio broadcasting to mobile devices and vice versa. Unlike other forms of frequency modulation, MSK produces a half sine wave that limits problems associated with non-linear distortion. What is GMSK? GMSK (Gaussian Minimum
