Oscillator block diagram.svg is the same image with A and β(jω) replaced with alternate variables G(jω) and H(jω). Oscillator diagram2.svg is the same image with the feedback loop shown broken, to show how loop gain is calculated.
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
b-c: The charge from the capacitor begins to flow through the bulb, instantly increasing the current to point b in the "abnormal glow" region of the curve. The bulb turns on. c-d: The voltage across the bulb and capacitor drops quickly to the extinguishing voltage V e at which the voltage is insufficient to continue ionizing the gas. The bulb ...
The light bulb repurposed as a positive temperature coefficient resistor is to the right of the upper section of the variable capacitor, which is the large structure in the center. The HP 200A , first built in 1938, was the first product [ 1 ] made by Hewlett-Packard and was manufactured in David Packard 's garage in Palo Alto, California .
English: Block diagram of a negative resistance electronic oscillator, illustrating the "reference plane" analysis method.The circuit consists of a differential negative resistance device such as a Gunn diode or magnetron tube connected to a resonator such as a LC circuit, dielectric resonator, or cavity resonator.

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.
