Abstract: An input current is applied to a ladder network comprising diode-connected-transistor shunt legs and resistive series arms. The network derives from the input current a bias current having an amplitude which is a fraction of the input current and supplies that bias current to the base-emitter junction of an amplifier transistor.

Abstract: A signal delaying circuit is coupled to a source of television video signals. A plurality of signal coupling circuits are coupled to the signal delaying circuit for developing a plurality of delayed video signals. At least a first and a second of the delayed video signals, spaced apart in time by a time interval substantially equal to NT/2, where T is the period of a signal component of the video signals and N is an integer greater than one, are combined to form a combined signal. A bandwidth determining signal is derived from at least a third of the delayed video signals spaced in time between the first and second delayed video signals. A peak response determining signal is derived by further combining the combined signal and the bandwidth determining signal. The amplitude of the peak response determining signal is controlled as a function of a control signal. In illustrative embodiments the apparatus is utilized to provide automatic luminance channel peaking and automatic color or chroma control (ACC).

Abstract: In the use of laser beams for alignment applications, such as surveying or range finding, the laser beam may be projected for a considerable distance through an ambient medium having a variation in its index of refraction. This will cause the laser beam to deviate from the desired straight line of reference during the surveying operation. The invention utilizes a laser beam having two or more beam components of different frequencies, respectively. If the laser beam deviates from the straight line of reference, the deviation of the beam components will be different and the spacing between the beam components at a distant point can be measured. From this spacing of the beam components, the correct straight line of reference can be determined and fixed relative to the position of one or more of the beam components.

Abstract: An oscillator which can be selectively started and stopped in response to a control voltage. When the oscillator is stopped, the control voltage is used to derive a voltage that is summed with the oscillator output such that the d.c. voltage level of the oscillator is the same value, both in the presence and absence of oscillations.

Abstract: A complementary field-effect transistor (FET) amplifier is biased to a given operating point by applying a reference potential to its input terminal and varying the operating potentials supplied to the amplifier in accordance with its output signal. At least one other complementary FET amplifier, integrated upon a common substrate with the first amplifier, receives operating potentials which also vary in accordance with the output signal of the first amplifier for maintaining the quiescent operating point of the other amplifier at a value substantially equal to the given operating point of the first amplifier.
