Parallel-tuned, series-fed Crystal Radio circuit |
The diode-clipped parallel-resonance voltage is output to the phones.
High-impedance diodes and phones are required to match the high impedance of the parallel-resonant
circuit.
This configuration is suitable for reception of distant, weaker stations.
2. Series-tuned, shunt-fed configuration:
Series-tuned, shunt fed Crystal Radio circuit |
The diode-clipped series-resonance current is output to the phones.
Low-impedance diodes and phones are required to match the low impedance of the series-resonant circuit.
This configuration is suitable for reception of nearby, more powerful stations.
3. Series-tuned, shunt-fed variant:
Series-tuned, shunt-fed Crystal Radio variant |
This is a variant of the above series-tuned, shunt-fed configuration.
Using low-impedance diodes and phones, it delivers identical performance.
