Abstract: 1,053,497. Ratemeters. STANDARD TELEPHONES AND CABLES Ltd. Oct. 18, 1963, No. 41236/63. Heading H3A. A ratemeter for deriving an indication which is a function of the frequency of an input signal, e.g. the beat frequency in a radio altimeter, comprises a pair of amplitude discriminator circuits to which the signal after limiting is applied, a capacitor which is discharged under the control of one discriminator when the amplitude of the input signal is more positive than a first predetermined value and charged under the control of the second discriminator when the amplitude of the signal is more negative than a second value and means for measuring the average value of the charge or discharge current. The input signal, Fig. 2A, is applied at terminal 20 to a first discriminator comprising diode 13 which is biased to a steady voltage indicated by line 30 and supplies output pulses 32, Fig. 2B, whenever the signal exceeds the steady value. These pulses bias a transistor 9 to its conducting state whereby capacitor 1 is discharged via transistor 11, diode 10 and transistor 9. The input signal is also applied to a second discriminator comprising diode 21 which is biased to a steady voltage indicated by line 31 and supplies output pulses 33, Fig. 2C, whenever the input signal is less than the steady value. These pulses bias off a normally conducting transistor 23 which in turn biases transistor 4 into its conducting state whereby capacitor 1 is charged via transistor 4 and diodes 5 and 6. The average value of the charge current through resistor 7 provides an indication of the frequency of the input signal.
