(a) Try to demodulate an FM signal on the edge of a lowpass filter
(b) Try to demodulate an FM signal with the same cutoff frequency as (a) on the edge of a highpass filter. How do the results differ?
(c) Repeat (a) and (b) with a realistic source signal (filtered noise).
(d) Design a phase detector according to Illustration 179.
(e) Try to replicate the experiment carried out in Illustration 180. (f) On your own design a PLL as in Illustration 181 and try to set the control voltage for the VCO in such a way that the PLL works.
The project has been broken down into the following modules: Power supply, Processor and motherboard with RAM, I/O circuit board, CD-ROM drive, Floppy drive LCD display, Keypad, Enclosure and all mechanical parts, Final assembly.
I. The passband edge frequencies of a BANDPASS BUTTERWORTH analog filter are 1200 Hz and 1400 Hz, whereas the stop band edge frequencies are 600 Hz and 2000 Hz. The stop band attenuation is 14dB.
A switch is made with an n-channel MOS device in a technology for which oxide thickness is 20 nm, minimum channel length is 1 um, unCox = 100 uA/V2, and VTH = 0.8 V. The devices operates in deep triode (i.e. small VDS)
Design an inverting amplifier using an ideal op-amp. the input resistance is 100kohms and the input voltage is 1V. A load resistor of 1kohms is connected to the output and must draw 5mW of power. find output voltage and current .
A man has set up a Christmas display using 20 strands of lights (500 Watts/strand). If the man wants to wire the strand outlets to the house panel with a 30 amp breaker, Determine a) The number of 30 amp parallel circuits Cratchit will have to wire..
1three resistors r1 r2 and r3 are connected in series and a supply voltage of 240 v. if r2 2r1 r3 3r1 and the total
how can i mix ticl4 and h2o? i want to prepare tio2 nanoparticles. what should be the ratio of ticl4 and water.
If the current line voltage is 460 V, what must the generator's operators do to correct for the low terminal voltage?
Let a crappy voice channel occupy 1kHz. To ensure no interefence between channels due to nonideal bandpass filters add a 3.0kHz spacing between channels. How many simultaneous voice channels can you have if allocated a 87MHz bandwidth total
Determine in each case whether the indicated signal x(t) isperiodic. If x(t) is periodic, find its fundamental frequence in Hzand fundamental period in seconds. a)x(t) = 3-5cos(1080t) + 7cos(2160πt) b)x(t) = 5sin(1080πt) - 7cos(3240πt)
A 3-bit binary counter counts for 0 (000) to 7 (111). The counter moves to the next state with an input of x = 0 and stays in the same state with an input of x = 1. a. Draw the State Table and State Diagram for this 3-bit binary counter.
two resistors with nominal values of 4.7K ohm and 10K ohm, are used in a voltage divider with a +15V supply to create a nominal +10V output. Assuming the resistor values to be exact, what is the actual output voltage produced
