100;
2. A dispersive delay of more than 10 µs; or
3. A 'frequency side‑lobe rejection' exceeding 65 dB and a bandwidth greater than 100 MHz;
Technical Note:
For the purposes of 3A001.c.1., 'frequency side-lobe rejection' is the maximum rejection value specified in data sheet.
2. Bulk (volume) acoustic wave devices which permit the direct processing of signals at frequencies exceeding 6 GHz;
3. Acoustic‑optic "signal processing" devices employing interaction between acoustic waves (bulk wave or surface wave) and light waves which permit the direct processing of signals or images, including spectral analysis, correlation or convolution;
Note: 3A001.c. does not apply to acoustic wave devices that are limited to a single band pass, low pass, high pass or notch filtering, or resonating function.
3. A. 001. d. Electronic devices and circuits containing components, manufactured from "superconductive" materials, specially designed for operation at temperatures below the "critical temperature" of at least one of the "superconductive" constituents and having any of the following:
1. Current switching for digital circuits using "superconductive" gates with a product of delay time per gate (in seconds) and power dissipation per gate (in watts) of less than 10‑14 J; or
2. Frequency selection at all frequencies using resonant circuits with Q‑values exceeding 10,000;
3. A. 001. e. High energy devices as follows:
1. 'Cells' as follows:
a. 'Primary cells' having any of the following at 20°C:
1.  'Energy density' exceeding 550 Wh/kg and a 'continuous power density' exceeding 50 W/kg; or
2.  'Energy density' exceeding 50 Wh/kg and a 'continuous power density' exceeding 350 W/kg;
b. 'Secondary cells' having an 'energy density' exceeding 350 Wh/kg at 20°C;
Technical Notes:
1. For the purposes of 3A001.e.1., 'energy density' (Wh/kg) is calculated from the nominal voltage multiplied by the nominal capacity in ampere-hours (Ah) divided by the mass in kilograms. If the nominal capacity is not stated, energy density is calculated from the nominal voltage squared then multiplied by the discharge duration in hours divided by the discharge load in Ohms and the mass in kilograms.
2. For the purposes of 3A001.e.1., a 'cell' is defined as an electrochemical device, which has positive and negative electrodes, an electrolyte, and is a source of electrical energy. It is the basic building block of a battery.
3. For the purposes of 3A001.e.1.a., a 'primary cell' is a 'cell' that is not designed to be charged by any other source.
4. For the purposes of 3A001.e.1.b., a 'secondary cell' is a 'cell' that is designed to be charged by an external electrical source.
5. For the purposes of 3A001.e.1.a., 'continuous power density' (W/kg) is calculated from the nominal voltage multiplied by the specified maximum continuous discharge current in ampere (A) divided by
