Normally an analog or digital output channel would be chosen.

An arrangement for monitoring a transducer, or detector, which produces an analogue or digital ouput signal corresponding to a state sensed by the transducer.

A digital-to-analog converter converts the digital output into an analog output.

A digital-to-analog converter converts the digital output signal into an analog signal.

The analog to digital converter (120) converts the analog output of the sensor to a digital value.

The analog to digital converter is adapted to convert an analog output of the sensor to a digital value.

Provides plurality of operation mode circuits (1-7) to accomplish the following digital input, digital output, analog input, analog output.

The ADC/DAC (112) is operable to perform both analog input signal analog-to-digital conversion and digital output signal digital-to-analog conversion.

A bandpass or lowpass filter has an input coupled to the analog output of the digital to analog converter and has a filtered output.

An audio output device receives the analog output form the digital to analog converter for producing audible output.

In one embodiment, a digital-to-analog converter receives a digital signal and outputs a first analog output signal corresponding to the digital signal.

An analog-to-digital converter generates a digital representation of said third frequency analog mixer output signal.

The N-bit digital-to-analog converter includes a digital signal input and an analog signal output.

An A/D converter for outputting a digital output signal obtained by digitizing an analog input signal.

The ADC samples the analog input and sends digital output to the digital subsystem.
