This present invention relates generally to devices, systems, and methods for performing optical and electrochemical assays and, more particularly, to devices and systems having universal channel circuitry configured to perform optical and electrochemical assays, and methods of performing the optical and electrochemical assays using the universal channel circuitry. The universal channel circuitry is circuitry that has electronic switching capabilities such that any contact pin, and thus any sensor contact pad in a testing device, can be connected to one or more channels capable of taking on one or more measurement modes or configurations (e.g., an amperometric measurement mode or a current drive mode).

Techniques for performing optical and electrochemical assays with universal circuitry

A receiver requiring only a single IF SAW filter and IF amplifier receives signals in both analog format and in digital format, such as the NTSC, PAL and SECAM analog television signal formats and the ATSC and DVB digital television signal formats. IF signals from the IF amplifier are sub-sampled to digital signal form and are processed by respective analog format and digital format processors. Control circuitry responsive to the presence of certain unique components of the signals in analog format and digital format determine which of the analog format and digital format processors is producing valid data and selects the valid data to be utilized. In a television receiver, the unique components of the signals may include carrier signals, synchronization signals, pilot signals and symbol timing, and valid data is applied to a television display.

Receiver for analog and digital television signals

A system for processing both a composite video television (TV) signal and a video cassette recorder (VCR) playback signal containing a combined line noise canceller and comb filter sharing a single delay line and a 3.58 MHz oscillator that drives a quadrature demodulator for demodulating both playback chrominance signals extracted from the playback signal and television chrominance signals extracted from the television signal. The system also provides automatic gain control to both the composite video TV signal and the VCR playback signal.
