Sleepytime For The Sleepyheads The Flipflop Frequency by The Paper Chase Lyrics
The marmosets are safe in one of their cozy nest holes. They rarely use the same sleeping place two nights in a row.
This simple diode modulator delivers excellent results when used for high percentage modulation at low signal levels. Constants are shown for a carrier frequency of about 10 MHz, but with a suitable tank, the circuit will give good results at any frequency at which the diode approximates a good switch. To extend frequency above that for which the IN4148 is suited, a hot-carrier diode can be substituted. A shunt resistor across the tank circuit can be used to reverse the circuit Q... reduce the circuit Q so as to permit high percentage modulation without appreciable distortion.
These are modulator circuits for modulation of video signals on a VHF/UHF carrier. The circuits require a 5V power supp... power supply and few external components for the negative modulation mode. For positive modulation an external clamp circuit is required. The circuits can be used as general-purpose modulators without additional external components. The IC is TDA6800.
This circuit permits direct connection of composite video signals from video games and microcomputers to the antenna terminals of TV sets.
By applying a variable M/S ratio flip-flop to these inputs, both speed and direction will be controlled. With RV1 in its center position the M/S will be 1:1... 1:1, whereby the motor will remain stationary due to its inability to track at the flip-flop frequency… the flip-flop frequency. Movement of RV1 in either direction will gradually alter the-
