An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt).
a) Find the power of the modulated signal.
b) Find the frequency deviation Δf.
c) Find the phase deviation Δφ.
d) Estimate the bandwidth of φEM(t)
how big will be capacitance connected on series with resistor R=30 omega in AC circuit with input voltage U1 = (200+2*17) V and frequency 50 Hz if the power factor is 0.7
mutual shifted by 90 degree currents through each of both windings of the single phase A motor are (5.5+1.7) A but RMS voltage of the supply is 220 V.How big will be torque on shaft of the motor is efficiency factor is 0.7.
For a particular IC-fabrication process, the transconductance parameter k'n = 50 µA/V2, and Vt = 1 V. In an application in which vGS = vDS =Vsupply = 7 V, a drain current of 0.8 mA is required of a device of minimum length of 2 µm.
