superheterodyne receiver

Armstrong was not the only person working on the idea of a superheterodyne receiver.

One major disadvantage to the superheterodyne receiver is the problem of image frequency.

This can be exploited as a frequency-changer in superheterodyne receivers.

Armstrong's superheterodyne receiver converted these high frequencies into one lower frequency.

The diagram at right shows the minimum requirements for a single-conversion superheterodyne receiver design.

Poor rejection of strong signals at adjacent frequencies compared to a superheterodyne receiver.

The radar operated at a frequency of 9,375 45 megahertz and used a superheterodyne receiver.

The superheterodyne receiver was invented in 1918 by Edwin Armstrong.

Superheterodyne receivers require a local oscillator and mixer, which required two tubes.

Superheterodyne receivers have essentially replaced all previous receiver designs.

The superheterodyne receiver offers superior sensitivity, frequency stability and selectivity.

This article only concentrates on the historical configurations leading up to and including the modern superheterodyne receiver design.

In the era of early radio, only the wealthy could afford to build a superheterodyne receiver (superhet).

For example, a key component of a superheterodyne receiver is a mixer used to move received signals to a common intermediate frequency.

Ceramic filters are frequently used in the IF stages of superheterodyne receivers.

Each student built a superheterodyne receiver, and fault-finding was taught using systematic signal-tracing.

He then built regenerative and superheterodyne receivers, and even transmitters.

Drawbacks to the superheterodyne receiver include interference from signal frequencies close to the intermediate frequency.

He patented the super-regenerative circuit in 1922, and the superheterodyne receiver in 1918.

He even built a superheterodyne receiver.

Local oscillators are used in the superheterodyne receiver, the most common type of radio receiver circuit.

The TR-1 was a superheterodyne receiver made with four n-p-n transistors and one diode.

Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly.

Cascode circuits are very useful as a multiplying mixer circuit in superheterodyne receivers.

Plate detectors are used in both T.R.F. and superheterodyne receivers.
