A resistance-capacitance parallel-T network is analyzed to find the conditions for a null in output and the transfer characteristic. Its use in the return circuit of a feedback amplifier is considered, and the bandwidth of the resulting tuned amplifier is found. The requirements for stability of the amplifier and for its use as an oscillator are discussed.
