NYQORA

NYQORA is a virtual laboratory for communications, optics and photonics. Predict, run, measure and report: 105 laboratories that run entirely on your phone or tablet. EVERY LABORATORY WORKS THE SAME WAY - Predict first: commit to an answer before the run. It is locked when you press Run, so the comparison is honest. - Run: set the parameters with sliders or typed values and read real instruments - oscilloscope, spectrum analyser, network analyser, optical power meter and more. - Understand: a block diagram of the system as a textbook draws it, how the bench is wired, and the formulas typeset with every symbol explained. - Measure: fill the measurement table and compare theory with simulation. Every measured reading comes with its 95 per cent interval. - Report: a PDF lab report with your predictions, results, answers and a run fingerprint, ready to hand in. NINE COLLECTIONS - Signals and Systems: sampling, the DFT, convolution, Fourier, Laplace and z transforms, FIR and IIR filter design, spectrograms, multirate, image filtering, speech - Analog Communication: AM, DSB-SC, SSB, VSB, FM and PM, each as modulation and demodulation, the superheterodyne, the PLL, the Costas loop, FM stereo - Digital Communication: PCM, TDM, delta modulation, line codes, eye diagrams, ASK, FSK, M-PSK and QAM with constellations, coding, Viterbi decoding, synchronisation - Wireless Communication: path loss, fading, Doppler, OFDM, equalisation, spread spectrum, multiple access, MIMO, channel estimation - RF Systems: spectrum analysis, amplifiers, noise figure, mixers, standing waves, Smith chart matching, S-parameters, couplers, microwave filters, TDR, waveguides - Antennas and Propagation: radiation patterns, gain, Yagi and helix, the microstrip patch - Optics: lenses, Gaussian beams, slits and gratings, Fourier optics, Michelson and Fabry-Perot interferometers, polarisation - Photonic Devices: lasers, LEDs, photodiodes, avalanche photodiodes, the Mach-Zehnder modulator - Fiber-Optic Communication: modes, numerical aperture, bend loss, dispersion, rise-time and power budgets, WDM, EDFA, Bragg gratings FIND IT, ZOOM IN Search by topic, instrument, formula or block - "Costas", "Hilbert", "BER". Every display and diagram opens full screen: pinch to zoom, and it is redrawn sharp rather than stretched. FREE AND PRO 19 laboratories are free, complete with their reports: every introductory one, the core of a first communications course, and at least one in every collection. NYQORA Pro, one purchase with no subscription, opens all 105 and adds export of any run as CSV, Python or MATLAB. PRIVATE BY DESIGN No account, no advertising, no analytics. Every laboratory runs on your device, offline. The only network request is the anonymous check for NYQORA Pro. By SCOPT Inc.
