摘要： Front end circuits and associated apparatus, systems, and methods for use in electronic devices such as buried utility locators are disclosed. The circuits include receivers and filters on input signals that are coupled to ground rather than differentially. A multiplexing circuit allows shared use of amplifiers, and analog-to-digital converters via a switching mechanism for selectively making or breaking electrical connection to the receiver channels for efficient sharing of electronics resources while minimizing crosstalk interference and advantageously reducing costs.

摘要： A marker device embodiment may include separate concentrically-oriented receive and transmit antenna elements coupled to an ASIC which includes electronics to receive an input signal at a first frequency from a transmitter, convert the input signal to a power supply to power the electronic circuit, generate, in response to the input signal, an output signal at a second frequency different from the first frequency, and provide the output signal, via the transmit antenna element, to an above-ground receiver for assistance in determining the location of a buried utility.
