High pass, low pass, and notch filters must be ...
Little Silver, New Jersey has a system of two Modulator 2008s and one 3012.

A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog ...
The Sup 'R' Mod II kit has a small printed circuit board, an antenna switch, and a coaxial cable with a ferrite core and RCA connectors.Composite video is received by the circuit board through a short cable terminating in a Molex connector, which plugs into a header on the Apple II motherboard.
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector ) is a circuit that performs demodulation , the inverse of modulation. A modem (from mod ulator– dem odulator), used in bidirectional communication, can perform both operations.
The company was founded by future Pennsylvania governor Milton Jerrold Shapp (the company name was derived from his middle name) in 1950. [1] The company was one of the earliest pioneers of community antenna television systems (cable television).
