Abstract: The object of the invention is a device for composing a number by means of a keyboard, by impedance variation. The lines are classified according to at least three categories of impedance, the system comprising means determining first the category of line measured or the zone and carrying out this measurement of the line impedance as soon as the device comprising measuring apparatus corresponding to the impedance zones and working in parallel, each measuring apparatus comprising comparators adapted respectively to the various categories of lines.

Abstract: Each repeater is fitted with a transmitter of a characteristic frequency located in the interband range of a n + n high-band and low-band link. By combining with a measuring frequency in the low band transmitted from the terminal station A, the nonlinearity of the repeater gives rise to a frequency in the high band which is received and measured in this same terminal station A.

Abstract: Receiver with a heterodyne preselector fed by a first local oscillator, oscillator, and a frequency converter having a manually controllable second local oscillator. In order to maintain the desired relation between the frequencies of the two local oscillators, the output signals therefrom are intermodulated and the frequency of the resulting signal maintained in a corresponding desired range of frequency by means of a circuit which, according to the value of the frequency of the resulting signal, (i) initiates a frequency sweep of the first local oscillator (ii) causes this frequency to be increased by a predetermined amount or (iii) causes this frequency to be decreased by a predetermined amount.
