Patent EP-1142112-B1 (EP)
Inventor: LYONS PATRICK JOHN
IPC: H04B1/38

Granted: 2005-04-20
Abstract: A narrow band radio receiver (1) comprises a signal mixer (5) which mixes the received signal with a variable frequency output signal received from a variable frequency signal generating circuit (6). A signal, the frequency of which is the difference between the frequencies of the received signal and the variable frequency output signal is relayed to an intermediate filter (10) which filters out signals of frequencies other than an intermediate frequency, which is similar to the difference frequency. The filtered signal is amplified and demodulated through an amplifier (12), demodulator (14) and is passed through an output circuit (15) where it is read by a microprocessor (16). On the microprocessor (16) determining that the signal is in valid format the signal is outputted through a gate (18). The circuit (6) is in the form of a phase locked loop circuit and a voltage controlled oscillator (23) generates the variable frequency output signal. A phase comparator (25) compares the signal frequency outputted by the voltage controlled oscillator (23) with a constant frequency signal from a signal generator (20) and applies a signal proportional to the phase difference to a control input port (28) of the voltage controlled oscillator (23) through an adder (30). A first switch (SW1) breaks the feedback loop (27) when the circuit has locked-up and a capacitive circuit (36) retains the DC voltage on pin (1) of the adder (30) at the locked-up voltage. The microprocessor (16) through a digital to analogue converter (32) applies a stepped staircase voltage to a pin (2) of the adder (30) which is added to the locked-up voltage which in turn causes the voltage controlled oscillator (23) to sweep the frequency of the variable frequency output signal through incremental frequency steps in a staircase fashion.
