Summary
DescriptionSuperheterodyne image problem.svg |
English: Diagram of the radio signals at different points in a superheterodyne radio receiver showing the problem of image response and why the receiver needs an RF image filter on the input. The horizontal axis is frequency while the vertical axis is voltage. The diagrams show what would happen in a superheterodyne without an RF filter.
In the superheterodyne the signal of the desired radio station (S1, blue) at frequency Русский: Графики радиосигналов в разных точках супергетеродинного радиоприемника иллюстрирующие возникновение и прохождение по тракту помехи с зеркальной частотой и поясняющая почему приемнику обычно необходим входной радиочастотный фильтр. По горизонтальной осотложена частота сигналов, а вертикальная ось — напряжение, или на красном графике коэффициент передачи фильтра в зависимости от частоты. На диаграммах показано влияние помехи по зеркальному каналу в супергетеродине без входного фильтра. В супергетеродине сигнал нужной радиостанции (S1, синий) на частоте |
