An electrical connector is adapted for mounting to a mounting surface of an electrical apparatus through the engagement of a vacuum-suction nozzle of a pick and place machine. The connector includes a dielectric housing having a first interface adapted to be positioned adjacent the mounting surface of the electrical apparatus, a second interface opposite the first interface and opposite side walls extending between the interfaces. A plurality of conductive terminals are mounted on the housing for interconnection to circuitry on the electrical apparatus. A removable cover is positionable on the housing over at least a portion of the second interface. The cover has a generally planar, smooth surface for engagement by the vacuum-suction nozzle. Slidable retention shoulders are provided between the cover and the side walls of the housing and are adapted to retain the cover on the housing with substantial force in a direction generally normal to the smooth surface of the cover. However, the slidable retention shoulders allow the cover to be mounted on and removed from the housing with minimal or zero force laterally of the normal direction.

A low profile hermaphroditic electrical connector is provided for mounting on the surface of a first printed circuit board and is adapted to mate with an identical second connector mounted on the surface of a second printed circuit board to electrically and mechanically couple the boards together. Each connector includes a housing mounting a plurality of stamped female and male terminals. Each terminal includes a surface mounting portion for electrically engaging the respective printed circuit board, a mating portion adapted to mate with the mating portion of the terminal of the opposite gender of the other hermaphroditic connector, and a portion for holding the terminal in the housing. The mating portion of the female terminal includes two opposed, spaced apart contact arms. The arms and the terminal holding portion both project from the mounting portion. The mating portion of the male terminal includes a contact post adapted to be received between the contact arms of the female terminal. The post and the terminal holding portion both project from the mounting portion. The male terminal includes a lip projecting beneath a shoulder on the housing to resist lifting of the surface mounting portion off the respective printed circuit board during unmating of the connectors.

An A/D converter converts a composite video signal to a digital signal. A bandpass filter extracts a chroma signal-A sinX from the composite video signal in digital form. A delay circuit delays the chroma signal-A sinX by 1/4 fsc to output-A cosX. Delay circuits delay the chroma signal-A sinX by 1/2 fsc to output A sinX. A ROM stores values of -(1 - cos.theta.) and sin.theta.. Values of -(1 - cos.theta.) and sin.theta. are read from the ROM in accordance with a phase modulation amount .theta. of a voltage controlled oscillator. A multiplier multiplies a value of sin.theta. read from the ROM and A cosX output from the delay circuit. A multiplier multiplies a value of -(1 - cos.theta.) read from the ROM and A sinX output from the delay circuit. An adder adds outputs of the multipliers. Delay circuits delays the composite video signal output from the A/D converter. An adder adds an output of the adder and the composite video signal output from the delay circuit.
