![]() 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.
