Abstract:
A receiver for various frequency bands, comprising:an oscillator for generating an oscillator signal at an oscillator frequency; and a frequency divider having an adjustable real divisor value, said frequency divider connected to receive said oscillator signal and to provide an output signal having a frequency of the oscillator frequency divided by the real divisor value; said frequency divider including a first multiplier having an adjustable integral multiplier value, and a first divider having an adjustable integral divisor value, said first multiplier connected in series with said first divider; when the receiver operated at a reception frequency range of 87 MHz to 108 MHz, said oscillator operated at an oscillator frequency range of 97.7 MHz to 118.7 MHz and the integral divisor value being 1 and the integral multiplier value being 1; when the receiver operated at a reception frequency range of 76 MHz to 91 MHz, said oscillator operated at an oscillator frequency range of 97.95 MHz to 120.45 MHz and the integral divisor value being 3 and the integral multiplier value being 2; when the receiver operated at a reception frequency range of 65.8 MHz to 74 MHz, said oscillator operated at an oscillator frequency range of 114.75 MHz to 127.05 MHz and the integral divisor value being 3 and the integral multiplier value being 2; when the receiver operated at a reception frequency range of 0.15 MHz to 0.282 MHz, said oscillator operated at an oscillator frequency range of 108.5 MHz to 109.82 MHz and the integral divisor value being 10 and the integral multiplier value being 1; when the receiver operated at a reception frequency range of 0.53 MHz to 1.71 MHz, said oscillator operated at an oscillator frequency range of 112.3 MHz to 124.1 MHz and the integral divisor value being 10 and the integral multiplier value being 1; and when the receiver operated at a reception frequency range of 0.513 MHz to 1.62 MHz, said oscillator operated at an oscillator frequency range of 112.13 MHz to 123.2 MHz and the integral divisor value being 10 and the integral multiplier value being 1.
