A signal is bandlimited to 12 kHz. The band between 9 and 12 kHz has been corrupted by excessive noise to the point that the information within this band is nonrecoverable. Determine the minimum sampling rate for this signal so that the uncorrupted portion of the band can be recovered. If we filter out the corrupted spectrum prior to sampling, determine the minimum sampling rate.
An FM transmitter delivers to a 75 ohm antenna a signal voltage of V(t) = 1000 sin ( 109t + 4 sin 104t ) Determine: (a) Carrier frequency (b) Intelligence frequency (c) Modulation index (d) Total power in FM signal (e) Carrier power (f) Power in e..
Calculate (by hand) the average output voltage, the Fourier series expressions of the currents, ia, ia1 and ia2 comment on the input line current harmonics.
A 2 GHz and 100 Watt transmitter is connected to a transmitter antenna with a gain of 12 dB. A 20 dB receiving antenna is placed 10 kilometers away, in what we assume to be free space, in the direction of maximum gain.
Charge densityrequired toproduce afield. Alayer of charge fills the space between x = -a andx = +a.The layer has a charge density p(x). The electric field intensity everywhere inside the charge distribution is given by E(x) = x&3, where K is a giv..
design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.
Find the total admittance YT in polar form. - Draw the admittance diagram. - Find the value of C in microfarads and L in henries.
design a system comprising a pulley actuated by a stepper motor to lift objects of maximum mass of 1kg. No gear box is required. A 48 VDC power source is available. Select a pulley (specify the diameter) and a stepper motor.
Sketch the PG network for a modified 16-bit Sklansky adder with fanout of [8, 1, 1, 1] rather than [8, 4, 2, 1]. Use buffers to prevent the less-significant bits from loading the critical path.
Consider a baseband transmission channel with a bandwidth of 10MHz. Which bit rates can be supported by bipolar line code and by Manchester line code
Show that the law of conservation of classical momentum is invariant under the Galiliean transformation if and only if total mass is conserved
