TLDR
In this article, a bridged-T network was used for the measurement of resistance, and was shown to be useful as the frequency-determining element of a resistance-tuned oscillator.Abstract:
A bridged-T network previously employed for the measurement of resistance is analyzed, and is shown to be useful as the frequency-determining element of a resistance-tuned oscillator The resistance-capacitance form of the network permits a wide tuning range and simple switching between ranges, while the resistance-inductance network suggests the possibility of building an oscillator having decade frequency dials With both forms of the network a moderate value of equivalent Q can be obtained, which is desirable for accuracy and stability of frequency calibrationread more

Improvements in the theory and design of RC oscillators
B. Stevens,R. Manning +1 more
TL;DR: In this article, it was shown that the best network for an RC oscillator cannot be established theoretically, and instead, the seven networks given fall into only three groups: the parallel-T network, the bridge oscillator network, and the transfer network.

A Wideband Digitally Controllable RFIC with Gain and Wavelength Tunability and Built-in Self Test Functionalities for Optical Transceiver Modules in FTTx Applications
TL;DR: In this paper, a wideband RF mixed-signal integrated circuit for optical transceiver modules in FTTx applications is presented, which has an operating frequency range of 700 MHz to 2.5 GHz and a gain which is tunable to the range of 31.5 dB in 0.5dB steps.

Improving the Response of a Bridged-T RC Network
S.C. Dutta Roy,Yashwant Joshi +1 more
TL;DR: In this paper , a modification of a bridged-T RC network, originally proposed by Sulzer, is presented for increasing the stop bandwidth and decreasing the notch level in the frequency response, which also gives the facility for fine tuning the notch frequency.

A New Type of Selective Circuit and Some Applications
TL;DR: In this paper, the inverse feed-back principle is used to obtain sharply selective circuits, where inductances are not necessary, and "tuning" can be changed by merely varying resistances.

Some Applications of Negative Feedback with Particular Reference to Laboratory Equipment
TL;DR: The use of feedback to an entire amplifier rather than just to the final stage of the amplifier makes it possible to realize the characteristics of a perfect amplifier over wide frequency ranges as mentioned in this paper.

Bridged-T Measurement of High Resistances at Radio Frequencies
TL;DR: In this article, a bridged-T circuit suitable to the measurement of high resistances at radio frequencies is analyzed and a measuring set incorporating the circuit is described, which is capable of measuring resistances ranging from 001 to 10 megohms with an accuracy approximating the precision of setting of the adjulstable standard elements of the apparatus.
