Patent EP-0375893-A2 (EP)
Inventor: HOF MANFRED DIPL-ING
IPC: H03L7/093
Filed: 1989-11-08
Abstract: A circuit arrangement for enhancing the frequency precision and reducing the circuit expenditure of a reference oscillator used in radio engineering, particularly for mobile radio telephones, is proposed in which the demodulated data frequency coming from the base station is used as reference frequency. The reference oscillator is corrected via a control circuit, the control voltage being obtained by taking into consideration the frequency of the reference oscillator and the data frequency. The reference frequency of the reference oscillator is selected in such a manner that it is an integral multiple of the data frequency. The frequency of the reference oscillator, after being divided, is compared with the data frequency. The signal resulting from the comparison is supplied to a D/A converter, the output voltage of which is supplied as control voltage to the control input of the reference oscillator. <IMAGE>

Abstract: 2.1 Random copolymers are known from the prior art. However, they still have severe disadvantages. The grip of tyre treads produced therefrom is inadequate, and these systems also have excessive wear. A further disadvantage is the slow vulcanisation of these copolymers. 
<??>2.2 Tyre treads made from the random AB block copolymers according to the invention have high wet grip and constant good wear, good dynamic properties and rapid vulcanisation. 
<??>2.3 The block copolymers according to the invention are suitable for the production of treads for car and lorry tyres, both for the production of new tyres and for remoulding of used tyres.

Abstract: A DTMF receiver (10) recognizes each of a plurality of multi-frequency tones, each tone centered on a predetermined standard frequency. Two digital bandpass filters (14, 16) each have four frequency bins, each frequency bin operating according to a recursive second-order transfer function for preferentially transmitting frequencies near the standard frequencies. Each frequency bin accumulates, for each of a plurality of sampling periods, respective spectral energy signals from the input signal. A temporal energy signal is derived from the spectral energy signals. For each bandpass filter (14, 16), a time-domain test template generator (30) and a frequency-domain test template generator (34) are provided to generate time-domain and frequency-domain test templates. These test templates are input to an analyzer (38) that compares the templates against data-adaptive frequency-domain and time-domain reference templates.
