Digital signal generator Exact frequency is 2^28/10 Hz. Used to drive a DDS synthesizer with 28-bit accumulator; gives output from 0 to 2.68435 MHz in 0.1 Hz steps. Instek SFG-1000 series is one example. 26.975 RC 27 MHz band, band 0/1 (grey/brown), "split" frequency; radio-controlled models of cars, boats, aircraft [29] 26.995 RC
Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound synthesizers and as part of ...
A master frequency generator or master electronic oscillator, in frequency-division multiplexing (FDM), is a piece of equipment used to provide system end-to-end carrier frequency synchronization and frequency accuracy of tones. The following types of oscillators are used in the Defense Communications System FDM systems:
A free-running oscillator which has a small amount of a higher-frequency signal fed to it, will tend to oscillate in step with the input signal. Such frequency dividers were essential in the development of television. It operates similarly to an injection locked oscillator. In an injection-locked frequency divider, the frequency of the input ...
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012). [2]In order to improve harmonisation in spectrum utilisation, the majority of service allocations stipulated in this document were incorporated in national tables of frequency allocations and utilisations which are within the responsibilities of the appropriate national ...
As the registers hold data for only a single line of the display, creating a full screen requires the game program to update the registers on the fly, a process known as "racing the beam". [ 10 ] To start the process, the game program running on the MOS Technology 6502 -based CPU loads the TIA's registers with the data needed to draw the first ...
A pendulum with a period of 2.8 s and a frequency of 0.36 Hz. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or repetitions per unit of time.
A completely different approach to function generation is to use software instructions to generate a waveform, with provision for output. For example, a general-purpose digital computer can be used to generate the waveform; if frequency range and amplitude are acceptable, the sound card fitted to most computers can be used to output the generated wave.
