Download Information Size Date Added Availability Compander A Compander allows the applicatino of unequal quantisation. This example shows the non-linear quantisation which can be achieved by using a Compander. 1.94K 22-06-2005 »Info on download »Download now Vector FFT/IFFT An example of a vector FFT/IFFT 3.01K 22-06-2005 »Info on download »Download now Phase Rotation The Phase Rotation block can be used to rotate any complex signal, in this case a QPSK constellation. The phase value can be either a constant (as in this example) or a varying phase term. 1.33K 22-06-2005 »Info on download »Download now Integrate & Dump The Integrate and Dump block is used to integrate a demodulated signal at a specified sybol rate, thus producing "Dumped" values suitable for Bit/Symbol detection 3.22K 22-06-2005 »Info on download »Download now A/D Converter A/D Converter 2.44K 22-06-2005 »Info on download »Download now An Oscilloscope This model contains an oscilloscope which can be triggered using either an Input Channel or via an External Trigger 2.61K 22-06-2005 »Info on download »Download now IQ Mapper Example The IQ Mapper block and IQ Detector block can be used to resepectively generate and detect arbitrary constellations in the IQ phase plane. 1.31K 22-06-2005 »Info on download »Download now Decimation block The Decimation block samples the input at the specified decimation rate, and can output either a Held or Zero Padded output 2.4K 22-06-2005 »Info on download »Download now Complex FFT The Complex FFT block outputs its result one sample at a time (this can be used to operate on the frequency domain signal just as any other signal (e.g. apply filtering etc) 1.73K 22-06-2005 »Info on download »Download now Modulo Block Example The Modulo block can operate in either integer mode or real mode 2.1K 22-06-2005 »Info on download »Download now Spectrum Analyser Spectrum Analyser display of a Baseband DPSK signal + noise 2.86K 22-06-2005 »Info on download »Download now Polynomial Block The Polynomial block implements up to a 5th order polynomial 1.87K 22-06-2005 »Info on download »Download now Phase Unrwap Block The Phase Unwrap block detects 2 Pi jumps when they occur, and unwraps the phase accordingly. The block can operate in either radians or degrees 2.44K 22-06-2005 »Info on download »Download now Phase Rotate Block The Phase Rotate block performs a complex multiply on the input signal to rotate it by the input phase value in radians 1.47K 22-06-2005 »Info on download »Download now Max Index Block Example The Max Index block is used to select which input is the largest 5.91K 22-06-2005 »Info on download »Download now Inverse FFT The FFT block performs a one-time FFT (or IFFT) and is controlled by an external trigger 3.01K 22-06-2005 »Info on download »Download now Gain (dB) Example The Gain block can be used to specify iether a gain or a loss in dB 1.85K 22-06-2005 »Info on download »Download now Conversions This model features the conversion of Real to dB, Power to dB, Re/Im to Mag/Ph and deg to Rad, and vice-versa 2.4K 22-06-2005 »Info on download »Download now Complex Exponential Example Complex Exponential Example 0.97K 22-06-2005 »Info on download »Download now Delay Block Example The Delay block is used in this example to synchronise the Real and Imaginary Parts of a complex signal being generated by taking th eHilbert transform of a real input signal. A Delay block is also used to delay the FFT trigger pulse so that the data interval for the FFT take sthe hilbert FIR delay into account 1.97K 22-06-2005 »Info on download »Download now Real Spectrum Analyser Real Spectrum Analyser display of a BaseBand DPSK signal 2.88K 22-06-2005 »Info on download »Download now
