The microphone came with a switch to tailor the mid-bass response, attenuating frequencies below 400 Hz with a mild high-pass filter. Like all premium microphones made by EV, it used EV's 1930s humbucker method of reducing electromagnetic interference by wiring a humbucking coil out of polarity with the microphone element coil. The microphone's ...
Shure SM7B microphone used in an interview with Marius Bear The Shure SM7 is a professional cardioid dynamic microphone , commonly used in broadcasting applications since 1973. Designed by Shure , it has been described as an "iconic" industry standard microphone for its focused, directional sound and its widespread adoption in radio, television ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

English: A typical electret microphone preamp circuit uses a FET in a common source configuration. The two-terminal electret capsule contains an FET which must be externally powered by supply voltage V +. The resistor sets the gain and output impedance. The audio signal appears at the output, after a DC-blocking capacitor.
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
A microstrip antenna array for a satellite television receiver Diagram of the feed structure of a microstrip antenna array. In telecommunication, a microstrip antenna (also known as a printed antenna) usually is an antenna fabricated using photolithographic techniques on a printed circuit board (PCB). [1] It is a kind of internal antenna.
A patch antenna is a type of antenna with a low profile, usually consisting of a printed circuit board. It consists of a planar rectangular or circular sheet or "patch" of metal, mounted over a larger sheet of metal called a ground plane. It is the original type of microstrip antenna described by Howell in 1972. [1]
