Modern electronic and communication systems rely on high precision timing and synchronization sources to ensure precision and reliability. Frequency Synthesis technology is used to calibrate and control the speed of the application and is a key enabling technology for advanced services such as digital audio broadcast, data broadcasting and digital wireless communication. A Pulse generator, or PGLFT for short, is a type of Frequency Synthesizer built for timing and synchronization purposes. It provides high accuracy, low phase noise, high resolution and is the most commonly used in applications such as wireline communications.

The term PGLFT represents both an application field and working principle. Regarding the application field, the most common application of PGLFT is wireless communication, which includes cell phones, wireless routers and access points, wireless broadcast systems and wireless consumer electronic products, where PGLFT is used as a component in the design of the communication circuit. For the working principle, PGLFT stands for pulse-generated frequency synthesizer, which is a type of Frequency Synthesizer based on a modulated and shaped clock or reference signal. It works by generating a sinusoidal wave-form that is frequency, phase and modulation locked to a clock (reference) source and is then processed through a pulse generator (PGL) and a filter circuit (LFT) before being fed through to the application.

The heart of any PGLFT application is the pulse generator component, also known as the pulse modulator, which is responsible for generating the frequency, phase and modulation signals. This component is a high-speed, high-frequency oscillator and amplifier circuit and typically consists of two parts. The first is a controlled oscillator that is used to generate the desired frequency, phase shift and modulation waveforms. This oscillator is coupled to a second amplifier circuit, which is used to drive the output signal of the pulse generator. The amplifier circuit is also typically used to control the amplitude and shape of the waveforms, which in turn provides control over the frequency, phase and modulation of the output of the pulse generator.

The output of the pulse generator is then filtered through a low-pass filter (LFT) to remove any unwanted higher frequency harmonics from the signal. The low-pass filter is designed to achieve a specific cutoff frequency, which is based on the desired application. This cutoff frequency is used to control the amplitude, frequency response, and phase response of the output signal. The filtered signal is then passed to the application, where it is used for timing and synchronization purposes.

PGLFT technology has become an integral part of many wireless communication systems due to its wide range of applications, such as providing synchronization in cell phone networks, providing timing information for digital audio broadcast systems, and controlling data transfer rates in digital wireless systems. Furthermore, PGLFT technology is also being used to power ultra-wideband (UWB) radio applications such as WiMAX broadband wireless access. The high accuracy and reliability of PGLFT has also been utilized in optical communication systems to provide precise timing reference signals for transmission of digital data.

In conclusion, PGLFT is an important tool for today\'s modern communication applications, providing high accuracy and low phase noise for timing and synchronization in various different communication systems. It is easy to integrate with existing systems and has proven to be a reliable and accurate source of timing and synchronization.
