Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz, finD:(a) the rms input noise levels (b) the audio output levels(c) the rms output noise levels
Let x1[n] = {-2,1,-3,-5,6,8} with arrow under -2 and x2[n]={1,2,3,4} with arrow under 1. a) determine circular convolution of 7 between x1[n] and x2[n] b) verify (a) calculations by computing the DFTs and IDFT.
Given the DSP system, where the sampling rate of 4000 Hz is used, the anti-aliasing filter is the Butterworth filter with a cut-off frequency of 200 Hz, and the percentage of aliasing level at the cut- off frequency is required to be less than 10%
Design a 2-digit 24 second "shot-clock" countdown timer with pushbutton controller.
An ideal C/D converter is followed by a discrete-time LPF which is followed by an ideal D/C converter. The sampling rate is 8000 samples per second. The input analog signal is bandlimited to 3900 Hz. The overall frequency response is required to s..
Analyze Case Study - NIBCO's 'Big Bang': An SAP Implementation- Explain the pros and cons of the approach to implementation decided upon by NIBCO.
The magnetization graph taken at 1800 rpm of a 6 kW, 120 V, 50 A, 1800 rpm, dc generator is attached below. Field resistance is 20 ohms and armature resistance is .18 ohms. Find: As a seperately excited generator
Design a 2-bit counter that, when v = 1, counts in the repeating sequence: 0, 3, 1, 2, and when v = 0, counts in the reverse direction. (a) Construct a state diagram and state table. (b) Implement the counter using D flip-flops.
Assume you buy a 1 kOhm resistor with +/- 20% tolerance in its value. You would like this resistor to consume at most 2 W of power, otherwise it might burn. What is the highest power supply in V you would use to power it
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 10 , inductive reactance XL = 20 , and a capacitive reactance XC = 10 . All three components are connected in parallel to the source.
Design an alarm circuit to be used in a process control system. Temperature (T), pressure (P), flow (F), and level (L) of a fluid are each monitored by separate sensor circuits that produce a high logic output signal when the following indicated p..
In comparing the behaviour of an n-channel MOSFET with a p-channel device having identical geometry and threshold voltage, it is found that the n-channel FET has a greater drain current than that of the p-channel FET.
AC Circit analysis and max power transfer, If the output impedance of a certain driving circuit is 50 Ohm - j10 Ohm, what value of load impedance will result in the maximum power to the load?
