We found this circuit in a 1967 IEEE documentation. The circuit uses discrete components of the time based on the 1.13 MHz frequency used with oscilloscopes at the time.
The circuit we use makes use of Linear Technology's LT3080 (www.linear.com) which consists of a...
This microcontrolled null adjustment for operational amplifiers was obtained in a Linear...
This is the receiver circuit for the previous transmitter. The circuit has a programming key to...
