PURPOSE:To improve modulation distortion, by providing a by-pass circuit in parallel with a differential pair inputting carriers, in an AM modulation circuit having the 1st differential pair and the 2nd differential pair taking one of a transistor (TR) forming the 1st differential pair as a ...
modulation was originally used to modulate audio voice signals onto a low-voltage direct current (dc) carrier on a telephone circuit.A microphone in the telephone handset acts as a transducer,and uses the sound waves produced by the human voice to vary the current passing through the circuit....
In this project, we proposed a Python GUI-based simulator to study Amplitude Modulation that is widely used by radio stations
For more on Scope setup and monitoring, see the "Scope Your Audio Modulation" page... There are several ways to monitor your transmitter AM audio. If you are using one of the more modern solid-state transceivers, you may have an AM monitor circuit built in. However, I have never heard...

The1N914 (or similar diode), 0.1uF capacitor and 1 megohm resistor allow a digital voltmeter to monitor the oscillator level. The best operating point will produce a meter reading near 0.7 volts with no modulation. These parts may be left out if the circuit is to be adjusted with a '...
A system and method for calibrating Amplitude Modulation to Phase Modulation (AM/PM) compensation circuitry in a mobile terminal operating according to a polar modulation scheme are
The device typically operates at a 1.5-MHz frequency pulse width modulation (PWM), at moderate to heavy load currents. Based on the VIN/VOUT ratio, a simple circuit sets the required off time for the low-side MOSFET, making the switching frequency relatively constant regardless of the ...
