American Radio Relay League

The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the United States.

See Crystal filter and American Radio Relay League

A band-pass filter or bandpass filter (BPF) is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. Crystal filter and band-pass filter are Linear filters.

See Crystal filter and Band-pass filter

Butterworth filter

The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. Crystal filter and Butterworth filter are Linear filters.

See Crystal filter and Butterworth filter

Ceramic resonator

A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached.

See Crystal filter and Ceramic resonator

Chebyshev filter

Chebyshev filters are analog or digital filters that have a steeper roll-off than Butterworth filters, and have either passband ripple (type I) or stopband ripple (type II). Crystal filter and Chebyshev filter are Linear filters.

See Crystal filter and Chebyshev filter

Crystal

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

See Crystal filter and Crystal

Crystal oscillator

A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element.

See Crystal filter and Crystal oscillator

Decibel

The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B).

See Crystal filter and Decibel

Electronic filter

Electronic filters are a type of signal processing filter in the form of electrical circuits. Crystal filter and Electronic filter are signal processing filter.

See Crystal filter and Electronic filter

FM broadcasting

FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave.

See Crystal filter and FM broadcasting

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force.

See Crystal filter and Global Positioning System

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception.

See Crystal filter and Intermediate frequency

Lattice network

A symmetrical lattice is a two-port electrical wave filter in which diagonally-crossed shunt elements are present – a configuration which sets it apart from ladder networks. Crystal filter and lattice network are Linear filters.

See Crystal filter and Lattice network

LC circuit

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.

See Crystal filter and LC circuit

Mechanical filter

A mechanical filter is a signal processing filter usually used in place of an electronic filter at radio frequencies. Crystal filter and mechanical filter are Linear filters and signal processing filter.

See Crystal filter and Mechanical filter

Piezoelectricity

Piezoelectricity is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress.

See Crystal filter and Piezoelectricity

Q factor

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. Crystal filter and q factor are Linear filters.

See Crystal filter and Q factor

QEX

QEX is a bimonthly magazine published by the American Radio Relay League.

See Crystal filter and QEX

Quartz

Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).

See Crystal filter and Quartz

Radio

Radio is the technology of communicating using radio waves.

See Crystal filter and Radio

Radio receiver

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form.

See Crystal filter and Radio receiver

Roofing filter

A roofing filter is a type of filter used in a HF radio receiver that limits the passband in the early stages of the receiver electronics. Crystal filter and roofing filter are radio technology and wireless tuning and filtering.

See Crystal filter and Roofing filter

Selectivity (radio)

Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel.

See Crystal filter and Selectivity (radio)

Signal generator

A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape.

See Crystal filter and Signal generator

Superheterodyne receiver

A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency.

See Crystal filter and Superheterodyne receiver
