The circuit of Figure 1 produces an accurate variable-frequency sine wave for use as a general-purpose reference signal. It includes an 8th-order elliptic, switched-capacitor lowpass filter (IC3) that ...

Journal of Coastal Research, Special Issue No. 97: Research, Monitoring, and Engineering of Coastal, Port, and Marine Systems (WINTER 2019), pp. 55-70 (16 pages) Nowadays, the design of wave energy ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Sine-wave generators with 0° to 360° phase-shifts are very important testing blocks in many systems involving DSP operations (i.e., I/Q modulator-demodulator ...

A Cornell doctoral student has developed an open-source software package that could transform how engineers design floating offshore structures for renewable energy and other ocean applications.

Harmonic drive systems represent a class of high‐precision, compact gear mechanisms built on the principle of strain wave transmission. Their unique design incorporates a flexible toothed component – ...

Vehicle designs ran the gamut at Solidworks World 2018, from those built by major car shops to small electric vehicles. The automotive industry has gone digital and independent. At Solidworks World ...

The WSE team has made a few live tweaks to the design during operation, improving its performance beyond original expectations. “We set out to prove that Wave Swell’s wave energy converter technology ...
