Definition: Attenuation is a process in physics and electrical engineering where an electrical signal or waveform is reduced by decreasing its amplitude. This can be achieved through various techniques, such as using filters, amplifiers, or other devices to reduce the output level of a signal. The goal of attenuation is to preserve the integrity of the original signal while reducing it to a manageable level.
Definition: Cogenial is a concept in physics that refers to the relationship between a generator and an oscillator. In other words, it describes how a generator can be used as an oscillator to generate a periodic signal. In simple terms, a generator converts electrical power into mechanical motion (oscillation). The oscillator, on the other hand, is a device that amplifies or attenuates the generated mechanical motion. This relationship allows for the generation of a periodic and stable oscillation in a circuit, which can be
Definition: Undercarry, also known as a "low-pass filter" or "bandpass filter," is a type of digital signal processing technique used to reduce noise and increase signal quality by filtering out unwanted frequencies. It works by applying a low-pass filter to the input signal, which means that it attenuates high-frequency components while allowing the low-frequency components through. Undercarry can be applied in various applications such as audio compression, video stabilization, and data compression. In the context of signal processing, undercarry
Definition: A racketer is a type of amplifier used in audio and video systems. It consists of an input transformer, an output transformer, and a diode or transistor that amplifies or attenuates the signal depending on its frequency content. Racketers are commonly used to amplify signals that need high levels of power but also have a limited bandwidth, such as FM radio signals or TV channels.
Definition: The word "low-pass filter" refers to a device or circuit that attenuates frequencies above certain thresholds, often used in audio or digital signal processing to remove unwanted noise or distortions. It works by filtering out low-frequency components at specific frequencies (often around 0.5 kHz) to create the desired spectral content of the input signal. The goal is to isolate the desired frequency range while maintaining the overall sound quality and bandwidth for the output.
