| 1. | Regenerative detectors were sometimes also used in TRF and superheterodyne receivers.
|
| 2. | The diagram has blocks that are common to superheterodyne receivers.
|
| 3. | The superheterodyne receiver has several advantages over previous receiver designs.
|
| 4. | This can be exploited as a frequency-changer in superheterodyne receivers.
|
| 5. | Edwin Howard Armstrong invented the superheterodyne receiver in 1918.
|
| 6. | Armstrong's superheterodyne receiver converted these high frequencies into one lower frequency.
|
| 7. | Superheterodyne receivers allow use one or more fixed intermediate frequency tuned circuits for selectivity.
|
| 8. | In 1918, Edwin Armstrong used only triodes when he invented the superheterodyne receiver.
|
