PURPOSE: A double shock wave inspecting device is provided to effectively inspect the shock resistance of equipment receiving double shock waves. CONSTITUTION: A double shock wave inspecting device comprises a speed generator assembly (1) and a trolley assembly (2) for collision. The speed generator assembly is operated by oil pressure or air pressure and generates a required speed by pushing a piston with high pressure. The trolley assembly for collision collides with a test bed (3) at a high speed, thereby generating positive acceleration, which is a primary waveform, by a spring. The trolley assembly for collision collides with a secondary waveform generator assembly (4), thereby generating negative acceleration, which is a secondary waveform, by the spring and a variable damper type waveform regulator assembly (5) operated by oil-and-air pressure or an MR fluid.

PURPOSE: A distance measurement signal processing device using a resolver and a method thereof are provided to detect a minimum value and a maximum value of amplified cosine wave signals and sine wave signals of the resolver, thereby accurately detecting a distance. CONSTITUTION: A distance measurement signal processing device using a resolver(10) comprises an amplifying circuit(120), a filter(130), an AD converter(140), and a micro computer(150). The resolver generates first cosine wave signals and first sine wave signals output according to a distance. The amplifying circuit amplifies the first cosine and sine wave signals into second cosine and sine wave signals. The filter removes noise of the amplified second cosine and sine wave signals.
