Granted: 1991-09-17
Abstract: ABSTRACT             A digital DTMF tone receiver comprised of a detector circuit for scanning incoming audio signals for possible presence of DTMF tones, and a verifier circuit for verifying the presence of the detected DTMF tones.  The detector circuit performs successive discrete Fourier transforms on the incoming signal at a first level of accuracy, and in response generates a tone verify flag signal for indicating whether or not a DTMF tone has been detected.  The verifier circuit is enabled in the event that the tone verify flag signal indicates detection of a DTMF tone.  The verifier circuit then performs further discrete Fourier transforms on the incoming signal at the detected DTMF frequencies as well as frequencies adjacent thereto, at a second level of accuracy greater than that provided by the detection circuit. The verifier circuit generates a tone present flag signal for indicating whether or not the detected DTMF tone is actually present.  The detector and verifier circuits are preferably implemented algorithmically within a digital signal processor.

Granted: 1991-09-03
Abstract: INDUCTANCE MULTIPLIER CIRCUIT   ABSTRACT      A circuit for increasing the apparent inductance presented by a transformer to a differential signal. The circuit may be used in a battery feed interface circuit for providing battery power to a subscriber's telephone or in a current sink interface circuit for providing a low impedance DC loop closure toward a telephone line feed circuit while maintaining a high impedance for differential AC signals.  In either usage the inductance multiplier  circuit  always  multiplies  the  primary inductance of the transformer by a factor which is one plus  a positive number.  The transformer has  three windings.   The multiplication is accomplished by a current source which provides to the third winding a current which flows therein in a manner so as to oppose the current flowing in that winding due to the voltage induced in that winding when the first and second windings are excited by the differential AC signal.
