A first switch (5) blocks the passage of the high-band (first frequency) signal and allows the low-band (second frequency) signal to pass.

A second switch (6) blocks the passage of the low-band (second frequency) signal and allows the high-band (first frequency) signal to pass.

The switch has a temporary second state in which it passes only the video picture signal.

The receive bandpass filter allows the received signal to pass therethrough but blocks the transmitted signal from the transmit feedhorn.

The data signal is passed through the limiter (52) giving rise to a sawtooth shaped phase error signal.

The plates are configured to allow the ultrasonic signal to pass therethrough.

Conversely, the transmit bandpass filter reflects the received signal received from the subreflector surface back towards the receive feedhorn while allowing the transmitted signal from the transmit feedhorn to pass therethrough.

 Building materials can impede the wireless signal.

A first stage common-emitter amplifier (16) provides high-gain amplification of the input signal, while a second stage amplifier (18) comprising an operational amplifier is suitable for driving a cable with the amplified sound signal.

A system according to various aspects of the present invention comprises a switch that includes: (i) a first state for allowing passage of a signal therethrough; and (ii) a second state for preventing passage of the signal therethrough.

The exposed part of the shield not covered by the layer of insulating material serves as a return electrode for the electrostimulation signal path.

In order to accomplish this, a unit must provide a clear channel for the signal to pass through.

This drug also obstructs the passing of the growth signal by stopping EGFR.

The frequency divided clocking signal transitions at a rate acceptable to a digital processor, while the PLL output clocking signal during an unlock state is not acceptable.

A first switch (5) blocks the passage of the high-band (first frequency) signal and allows the low-band (second frequency) signal to pass.
