Analyze and design different oscillator circuits

One resistor | Use the same resistor to charge and discharge a capacitor |

Two resistors | Use one resistor for charging and another resistor for discharging a capacitor |

Combined resistor | One resistor is used for both charging and discharging, the other only for charging |

555 oscillator | The classic 555 oscillator circuit |

555 timer | The classis 555 timer circuit |

Threshold | Select between specifying the threshold in absolute volts or in percents of the charge voltage |

Uchg/dis | The voltages use to charge and discharge the capacitor, Uchg is usual the supply voltage and Udis is usual 0 volt |

Threshold | The level where the oscillator switch between charge and discharge |

R or Rchg/dis | The resistor(s) used to charge/discharge the capacitor |

C | The capacitor used |

Time | Charge/discharge time when designing a circuit |

Oscilloscope | Shows waveforms from different parts of the circuit |

R Rchg, Rdis | Calculated resistors |

Time | Time for charge/discharge or total time |

Charge added/removed | Charge added or removed when charging/discharging |

Max. current | Maximum current in resistor/capacitor during charge/discharge |

Min. current | Minimum current in resistor/capacitor during charge/discharge |

Tau | The product of R and C |

Frequence | Oscillating frequence |

Duty cycle | Duty cycle of oscillation |
