Wireless tuning and filtering

Amplifier

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current).

See Roofing filter and Amplifier

Amplitude modulation

Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.

See Roofing filter and Amplitude modulation

Band-pass filter

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.

See Roofing filter and Band-pass filter

Bandwidth (signal processing)

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

See Roofing filter and Bandwidth (signal processing)

Clipping (signal processing)

Clipping is a form of distortion that limits a signal once it exceeds a threshold.

See Roofing filter and Clipping (signal processing)

A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration.

See Roofing filter and Continuous wave

Crystal filter

A crystal filter allows some frequencies to 'pass' through an electrical circuit while attenuating undesired frequencies. Roofing filter and crystal filter are radio technology and wireless tuning and filtering.

See Roofing filter and Crystal filter

Digital signal processing

Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations.

See Roofing filter and Digital signal processing

Frequency mixer

In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it. Roofing filter and frequency mixer are radio electronics.

See Roofing filter and Frequency mixer

Hertz

The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second.

See Roofing filter and Hertz

High frequency

High frequency (HF) is the ITU designation for the band of radio waves with frequency between 3 and 30 megahertz (MHz).

See Roofing filter and High frequency

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. Roofing filter and intermediate frequency are radio electronics.

List of Institution of Engineering and Technology academic journals

This is a list of journals published by Institution of Engineering and Technology (IET), including those from its predecessors Institution of Electrical Engineers (IEE) and Institution of Incorporated Engineers (IIE).

Mechanical filter

A mechanical filter is a signal processing filter usually used in place of an electronic filter at radio frequencies.

See Roofing filter and Mechanical filter

Modulation

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. Roofing filter and modulation are radio technology.

See Roofing filter and Modulation

Passband

A passband is the range of frequencies or wavelengths that can pass through a filter.

See Roofing filter and Passband

Preselector

A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver. Roofing filter and preselector are radio electronics, receiver (radio) and wireless tuning and filtering.

See Roofing filter and Preselector

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. Roofing filter and radio receiver are receiver (radio).
