Draw the circuit diagram of a first-order RC lowpass filter and give the expression for the half-power frequency in terms of the circuit components. Sketch the magnitude and phase of the transfer function versus frequency.
Design a sequence generator circuit with 4 outputs W,X,Y and Z. The circuit should generate the following sequence of output patterns: 0001, 0011, 1100, 1000. After 1000, the circuit should repeat the sequence starting at 0001 again.
a signal st is defined as st 4cos3pit 5cos21pit volts. the signal st is sampled using ideal sampling with a
The current in a circuit is 100mA. Determine what the current will be when the resistance is increased by 100%.
A recent study has been carried out concerning radio propagation in railway tunnels. In this study, two railway tunnels of rectangular cross section are considered. Tunnel 1 has transverse dimensions of width a = 8 m
If the frequency of a signal is 120 Hz and the sampling frequency is 150 Hz, what is the aliased frequency of the signal
Polonium (Po) is the only material which forms a simple cubic crystal (i.e., it is not FCC or BCC) structure with atoms at the corner positions. It is a metal (but it is radioactive so it has very few engineering applications!). Its atomic number ..
A short distance system is composed of two identical transmission lines with an amplifier between them. A 1 mW signal is transmitted at one end and is received at the other end with an SNR of 22 dB.
Find the propagation delay for a minimum-size inverter for which Kn' = 3 Kp' = 180 uA/V^2 , and (W/L)n = (W/L)p = 0.75 um/0.5 um , VDD = 3.3 V , Vtn = -Vtp = 0.7 V, and the capacitance is roughly 2
A thin spherical shell of 0.4 kg and a diameter of 0.2 m is filled with alcohol of density 800 kg/m^3. It is released from rest at the bottom of a container of water. Calculate the acceleration of the shell as it rises to the surface.
1. Design a synchronous Mod-10 up counter from 1st principles nusing K-MAPS. Use Diagram 1(insert answer book) and also draw the final counter in your book. 2. Draw a MOD-10(5-bit) Johnson counter using D-bistables.
Use a capacitor, a resistor and an operational amplifier circuit to design an active first order low pass filter which passes frequencies that human can hear (below 15kHz). Show all the calculations required to find the values of all the passive comp..
Given the following function: F(W,X,Y,Z) = fm(2,3,5,7,12,13). a. Implement the function using an 8-input multiplexer. b. Implement the function using a 4-input multiplexer.
