FM Bug Transmitter. Take a look at this fm spy transmitter which can be used as a bug transmitter or as fm bug too. It uses a single IC 74F13, one coil, a capacitor, one trimmer, one resistor and ...

This mosfet fm transmitter circuit is designed to be used for aligning FM radio receivers. It has a microphone amplifier with automatic gain control. The FM modulation is a voltage oscillator and the ...

Report 1965-48. Compatible single-sideband modulation: Comparisons with double-sideband modulation over high-frequency circuits ...

In the transmitter circuit of the pacemaker, pulse width modulation (PWM) technology is applied to further reduce power consumption and adapt to process variations. The conventional method to generate ...

Abstract. Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare ...
