Analog generators contain frequency-sensitive circuits for self-excitation condition at the specified frequencies.
As a rule arbitrary waveform generator is a sort of function generator capable of generating arbitrary waveforms. The majority of modern arbitrary waveform generators use direct digital synthesis (DDS) to generate an output signal, i.e. they are digital.
Amplitude shift keying is a signal transform method when the carrying oscillation amplitude changes abruptly depending on the discrete data messages.
DDS is a rather new frequency synthesis method which appeared in early 70s, last century. All the methods described have been available to the developers for decades but only recently such a close attention has been paid to DDS. Nowadays the appearance of cheap micro circuits with DDS and convenient development tools make them attractive for various application fields.
In frequency Modulation a carrier is more high-frequency comparing to the information signal and frequency-modulated signal amplitude is steady.
Frequency shift keying is a signal transform method when the carrying oscillation frequency changes abruptly depending on the discrete data messages.
As a rule function generator is a sort of a waveform generator capable of generating different signal waveforms (there are usually 3 typical signals: sine, square, triangle/sawtooth).
Keying is the transition process of one or several high-frequency signal (which is called carrier) parameters under the law of low-frequency discrete data message.
Logic sequence generator, pattern generator is a technical device, generator which forms signals to work with digital electronic circuits on several outputs at the same time.
The main modulation function is signal transformation or transfer from low-frequency range to higher for further transfer through radio or cable carrier line.
Phase Modulation is analog signal (carrier) transformation type when the signal changing parameter is its phase.
Phase shift keying is a signal transform method when the carrying oscillation phase changes abruptly depending on the discrete data messages.
A pulse is a sporadic increase or decrease in a current flow. Idealy the pulse would have a rise and a fall. Pulse generator is a source of pulse signals for the regulation of measurements in electronic circuits and instruments.
Pulse Width Modulation (PWM) is signal duty changing (Duty is ratio pulse width to signal period).
Innovative SiFi (Signal Fidelity) technology provides signal generation on “point by point” principle. This technology helps to achieve the best quality of the generated signal with low jitter, low distortion level and high precision of frequency setting.
A signal is a waveform that carries information. Signals can be AC or DC.
The simplest generator circuit can be assembled using logical elements. The main advantage of this generator is nothing superfluous: a timing RC chain and two microcircuit elements.
A square pulse generator built on the basis of the popular 555 microcircuit works as a multivibrator i.e. in self-oscillating mode. This is a mode in which impulses arise themselves, without any external influences.
