Title: Automatic gain control circuit
Inventor: FUJITA SUSUMU
IPC: H03G3/00
Filed: 1981-08-11
Abstract: PURPOSE:To make an output level constant independently of an input level by controlling the gain of an amplifier so that the number of counts of a pilot signal converted into a square wave at high level period can be within the number of counts set to a discriminator. CONSTITUTION:A carrier wave inputted to an input terminal 1 is amplified at an amplifier 3, outputted at an output terminal 7 and applied to a filter 21 for the pickup of a pilot signal. The pilot signal picked up from the filter 21 is compared with a reference voltage from a reference voltage generator 23 at a voltage comparator 22 and converted into a square signal. The pilot signal converted into the square wave signal is applied to a counter 24, which counts a frequency from an oscillator 25 only when the pilot signal is at high level. The output of count is inputted to an encoder 26 to form a code signal for the control of a resistance circuit network 27 and gives the count output also to a discriminator 28. The parameters of the network 27 are controlled with the code signal output and the change in the parameters controls the gain of the amplifier 3.

Title: Amplitude modulator
Inventor: AKAIWA YOSHIHIKO
IPC: H03C1/14
Filed: 1977-10-24
Abstract: PURPOSE:To avoid the fluctuation of the modulation degree caused by the temperature by adding the bias circuit featuring the temperature characteristics to the amplitude modulator and then controlling the output change of the oscillator due to the temperature change via the increase and decrease of the bias current. CONSTITUTION:The output of oscillator 1' is applied to modulation diode 2', and the bias current applied to diode 2' is changed over by switch 3. This switching is carried out in correspondence to the value which is decided by the voltage and current connected to bias terminal 5' and 6' according to the modulation signal input 4. In this way, however, the modulation fluctuation due to the temperature is produced at the output emerging at output terminal 8' of circulator 7'. In this connection, the bias circuit consisting of current source 9 which does not change by the temperature and current source 10 which changes by the temperature is added previously to bias terminal 5'. As a result, the current flowing to diode 2' is set to difference current I1-I2 between two current sources 9 and 10 in order to keep the degree of modulation constant.
