A blocking oscillator (sometimes called a pulse oscillator) is a simple configuration of discrete electronic components which can produce a free-running signal, requiring only a resistor, a transformer, and one amplifying element such as a transistor or vacuum tube.

crystal oscillator An electronic oscillator whose frequency is stabilized by a piezoelectric crystal resonator element. Ćuk converter One kind of buck-boost voltage converter that uses a capacitor as an energy storage element. current The movement of electric charge. current density The current flowing per unit area of a conductor. current ...
This circuit compares the frequency of a controlled oscillator to the reference, automatically raising or lowering the frequency of the oscillator until its frequency (but not necessarily its phase) is matched to that of the reference. A frequency-locked loop is an example of a control system using negative feedback. Frequency-lock loops are ...
English: Abstract block diagram of an electronic oscillator. It consists of an amplifying element with transfer function G(jω) with its output fed back into it's input through a feedback network with transfer function H(jω). The output voltage is labelled V o and the feedback voltage is labelled V f.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. [1] [2] [3] These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and ...
