A matrix router and method of switching comprising a combined input stage and output stage (I/O stage) having m matrix switch(es), each matrix switch having n inputs and n outputs, each input of said n inputs switchable within said matrix switch to any output of said n outputs, k core outputs and k core inputs, each input of said n inputs switchable to any core output of said k core outputs and each core input of said k core inputs switchable to any output of said n outputs; and a core stage having a matrix switch at least with m times k core stage inputs and at least m times k core stage outputs, each core stage input connected to one core output of said I/O stage, and each core stage output connected to one core input of said I/O stage, where m, n and k are integers and m&#x2267;1, n&#x2267;2, k&#x2267;n.

Matrix router and method of switching

An encoder. The encoder includes an analog-to-digital (A/D) converter that receives an analog signal. The A/D converter downconverts and digitizes the analog signal without analog mixing of the analog signal. The encoder also includes a resampler that is coupled to the A/D converter. The resampler receives the digital signal and converts the downconverted digital signal to an output signal at a data rate independent of a data rate of the digitized analog signal.

Architecture for intermediate frequency encoder

An automatic gain control circuit for an analog to digital converter is provided. The automatic gain control circuit includes an input, coupled to an output of the analog to digital converter, to receive samples output by the analog to digital converter. The automatic gain control circuit also includes a digital to analog converter that is coupled to selectively adjust a magnitude of an input signal for the analog to digital converter. The automatic gain control circuit also includes a microcontroller. The microcontroller is coupled to the input and the digital to analog converter. The microcontroller is programmed to generate a feedback signal for the digital to analog converter to control the amplitude of the input to the analog to digital converter.
