Connect the two signals used in section 2 above to the "Multiplier" module. Make sure that you record the amplitude of each signal.
Observe and record the resultant waveform in both the time and frequency domain, noting all the important characteristics.
Note:You can synchronise the CRO or Picoby connecting the 2 kHz message to the "Ext" input of the PicoScopeand selecting the "External Trigger". This will result in a stable trace on the oscilloscope.
Q. For DSB and conventional AM, obtain expressions for the in-phase and quadrature components x d (t) and x q (t), and envelope and phase v(t) and φ(t).
Q. Define Transconductance? The control that the gate voltage has over the drain current is measured by the transconductance gfs and is similar to the transconductance gm of t
A DC shunt motor rotating at 1560 RPM is supplied from a 240-V source. The line current supplied to the motor is equal to 27 A. The shunt field resistance of the motor is equal to
