H03D13/001in which a pulse counter is used followed by a conversion into an analog signal H03D13/002the counter being an up-down counter H03D13/003in which both oscillations are converted by logic means into pulses which are applied to filtering or integrating means H03D13/004the logic means delivering pulses at more than one terminal H03D13/005in which one of the oscillations is, or is converted into, a signal having a special waveform H03D13/006and by sampling this signal by narrow pulses obtained from the second oscillation H03D13/007by analog multiplication of the oscillations or by performing a similar analog operation on the oscillations H03D13/008using transistors H03D13/009using diodes
