The rf output voltage should be proportional to the signal voltage in AM. A change in the DC supply voltage should also cause a proportional change to the rf output voltage.
a constant amplitude supply
a constant amplitude supply
The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.
it will run in same direction because flux and armature current both will be changed wih plarity.
supply will decrease
supply will increase.
In video signals (US), Hum modulation is a 60 Hz. interference which manifests as bars of distortion rolling slowly from bottom to top in the picture. This is always a product of A.C. interference in an "active" component (e.g. power supply).
AC source of electric power changes changes polarity constantly, in amplitude.
You need to assess the frequency, amplitude and see if there is any distortion in the waveform. The best way is with an Oscilloscope.
If supply of a commodity decreases, the supply will fall. Prices and supply of good have positive relationship.
Supply is inelastic and demand is elastic for land.
there is a shift in the supply curve when the cost of input rises.
